Suppose 550 g of water at 32 degrees * C is poured into a 210 - g aluminum can with an initial temperature of 15 degrees * C . Find the final temperature of the system, assuming that no thermal energy is exchanged with the surroundings.

Answers

Answer:

about 30.714degC

Explanation:

Assuming

specific heat of water at  4200 J/kg * K

specific heat of aluminum 900 J/kg * K

(actual values to higher precision differ, and also change slightly with temperature).

To raise the aluminum's temp by 1K we need 900J * (210g / 1kg) = 189J

189J given by the water decreases its temp by 1K * (189J / 4200J) * (1kg / 550g) = 0.0(81)K.

So every K the temp of aluminum rises, 0.0(81)K falls the temp of the water.

At a difference of (32degC - 15degC) = 17K, we infer the temp will balance out after 17K / (1K + 0.0(81)K) "steps", so about 15.714.

The final temperature will be around 30.714degC

The final temperature of the water-aluminum mixture is 30.7 ⁰C.

The given parameters;

mass of the water, = 550 ginitial temperature of the water, = 32⁰Cmass of the aluminum, 210 ginitial temperature of the aluminum = 15⁰ Cspecific heat capacity of water = 4.184 J/g⁰Cspecific heat capacity of aluminum = 0.9 J/g⁰C

The final temperature of the mixture is determined by applying the principle of conservation of energy;

Heat lost by the water = Heat gained by the aluminum

[tex]mc_w \Delta t = mc_{AL} \Delta t\\\\550 \times 4.184 \times (32 - t) = 210\times 0.9 \times (t - 15)\\\\73638.4 - 2301.2t = 189t - 2835\\\\76473.4 = 2490.2t\\\\t =\frac{76473.4}{2490.2} \\\\t = 30.7 \ ^0C[/tex]

Thus, the final temperature of the water-aluminum mixture is 30.7 ⁰C.

Which statement accurately describes viscosity?
A. A liquid with larger molecules resists movement more than a liquid with smaller molecules does.
B. A material slows or completely blocks the flow of electrons through it.
C. A material with relatively weak bonds between its particles can be shaped into a thin sheet.
D. Attractive forces between molecules at the surface cause a liquid to resist spreading out.​

Answers

The statement that accurately describes viscosity is option D: Attractive forces between molecules at the surface cause a liquid to resist spreading out. Option D

Viscosity is a measure of a fluid's resistance to flow. It quantifies how easily a fluid can be deformed or how readily it flows. In liquids, viscosity arises from the cohesive forces between molecules.

When molecules in a liquid are attracted to each other, they tend to stick together and resist movement. At the surface of the liquid, there is a greater degree of attractive forces between the molecules since they have fewer neighboring molecules to interact with.

This surface tension creates a resistance to the spreading out of the liquid and causes it to exhibit a more rounded or droplet-like shape.

The attractive forces between molecules at the surface of a liquid contribute to the cohesive forces within the liquid as a whole, resulting in a higher viscosity.

The stronger the attractive forces between the molecules, the higher the viscosity of the liquid. For example, honey has a higher viscosity compared to water because the molecules in honey have stronger attractive forces, making it flow more slowly.

Option A is not an accurate description of viscosity. Viscosity is not solely determined by the size of the molecules in a liquid but rather by the strength of the attractive forces between the molecules.

Option B describes electrical conductivity, not viscosity. It refers to a material's ability to slow down or impede the flow of electrons.

Option C describes the property of malleability, not viscosity. It refers to a material's ability to be shaped into a thin sheet without breaking.

Therefore, option D accurately describes viscosity by highlighting the role of attractive forces between molecules at the surface of a liquid in resisting the spreading out of the liquid

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool (see Figure 1), and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.
Some of the earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC, and appears to have had a good understanding of how light is reflected. However, it wasn't until a millennium and a half later that the Arab scientist Alhazen proposed a law describing exactly what happens to a light ray when it strikes a smooth surface and then bounces off into space.

To what temperature will a 50.0 g piece of glass raise if it absorbs 5275 joules of heat and its specific heat capacity is 0.50 J/g°C? The initial temperature of the glass is 20.0°C.

Answers

Answer:

Final temperature, T2 = 131895°C

Explanation:

Given the following data;

Mass = 50g

Initial temperature = 20°C

Quantity of heat = 5275J

Specific heat capacity = 0.50 J/g°C

To find the final temperature;

Heat capacity is given by the formula;

[tex] Q = mcdt[/tex]

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Making dt the subject of formula, we have;

[tex] dt = \frac {Q}{mc} [/tex]

Substituting into the equation, we have;

[tex] dt = \frac {5275}{50*0.50} [/tex]

[tex] dt = \frac {5275}{25} [/tex]

dt = 131875°C

Now, the final temperature T2 is;

But, dt = T2 - T1

T2 = dt + T1

T2 = 131875 + 20

T2 = 131895°C

The final temperature when a glass piece absorbs heat  5275 joules  will be  T2= 231 C

What is heat capacity?

The heat capacity is defined as the amount of heat any material can absorb when the temperature is changed to unit quantity.

Given the following data;

Mass = 50g

Initial temperature = 20°C

Quantity of heat = 5275J

Specific heat capacity = 0.50 J/g°C

To find the final temperature;

Heat capacity is given by the formula;

[tex]Q= mc(T_2-T_1)[/tex]

Where;

Q = represents the heat capacity or quantity of heat.

M= represents the mass of an object.

C= represents the specific heat capacity  

T1= initial temperature

T2 = Final temperature

Substituting into the equation, we have;

[tex]Q=mc(T_2-T_1)[/tex]

[tex](T_2-T_1)=\dfrac{Q}{mc}[/tex]

[tex](T_2-T_1)=\dfrac{5275}{50\times 0.50}[/tex]

[tex]T_2=211+T_1[/tex]

[tex]T_2=211+20=231 ^oc[/tex]

Thus the final temperature when a glass piece absorbs heat  5275 joules  will be  T2= 231 C

The graph show a distance travelled by four cars (A, B, C& D) over a period of time . Which car travelled at a greatest speed? *

Answers

Answer:

Car A traveled with the greatest speed.

Explanation:

We know that the steepness of the slope of the line on the distance-time graph represents speed.

Important Tip:

If the slope of the line is more vertical — steep — the speed will be fast.If the slope of the line is more horizontal — flatter — the speed will be slow.

For example, at t = 5 seconds, the A car has covered more than 80 meters while all the other cars have covered less than 80 meters during the same period.

IIn fact, during the entire journey, it is clear that from the graph that the slope of the line of A car is more vertical — steep — than the slopes of cars B, C, and D.

Therefore, car A traveled with the greatest speed.

A man pushed the box with a force of 20 N. The mass of the box doubled, but he still pushed with a force of 20 N.
Which option describes how the acceleration of the box after the mass was doubled?

a) The acceleration is 2x the original acceleration

b) Acceleration is 4x the original acceleration

c) Acceleration is 1/2x the original acceleration

d) Acceleration is 1/4x the original acceleration

Answers

Answer:

Option (c) Acceleration is 1/2x the original acceleration

Explanation:

To know the the correct answer to the question, we shall determine the acceleration of the box in each case.

Case 1:

Mass (m) = m

Force (F) = 20 N

Acceleration 1 (a₁) =?

F = ma₁

20 = m × a₁

Divide both side by m

a₁ = 20 / m

Case 2:

Mass (m) = 2m

Force (F) = 20 N

Acceleration 2 (a₂) =?

F = ma₂

20 = 2m × a₂

Divide both side by 2m

a₂ = 20 / 2m

a₂ = 10 / m

Finally, we shall determine the acceleration of the box after the mass was doubled. This can be obtained as illustrated below:

Acceleration 1 (a₁) = 20 / m

Acceleration 2 (a₂) = 10 / m

a₂ : a₁ = 10 / m : 20 / m

a₂ / a₁ = 10 / m ÷ 20 / m

a₂ / a₁ = (10 / m) × (m / 20)

a₂ / a₁ = ½

Cross multiply

a₂ = ½a₁

Thus, the acceleration of the box after the mass was doubled is ½ times the original acceleration.
