Explanation:

Why does an increase in temperature result in an increase in reaction rate?

Answers

Answer:

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.

Answer:

When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.

can you give me an example about radiation

Answers

Explanation:

 A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.

Answer: The energy from the sun is one great example of radiation. The sun emits light in a broad range of wavelengths which all contain energy. These waves are also discussed in the climate section for energy balance. The waves are emitted from the sun and travel through space and hit the earth and other planets.

EXTRA EXAMPLES: heat from a stove burner.

visible light from a candle.

x-rays from an x-ray machine.

alpha particles emitted from the radioactive decay of uranium.

sound waves from your stereo.

microwaves from a microwave oven.

electromagnetic radiation from your cell phone.

At 10°C, the gas in a cylinder has a volume of 0.250 L. The gas is allowed to expand to 0.285 L.


What must the final temperature be for the pressure to remain constant? (Hint °C + 273 = K.)


282 K


284 K


323 K


248 K

Answers

Explanation :Use the formula: P1V1T1=P2V2T2
We know that we want P1=P2 so the pressure will remain constant, so we can say that: P1V1T1=P1V2T2
Plug in the values we know: P1⋅0.250L283K=P1⋅0.285LT2
(Remember that temperature must be done in Kelvin.)
Cross multiply: T2⋅P1⋅0.250L=283K⋅P1⋅0.285L
Divide both sides by P1.
T2⋅0.250L=283K⋅0.285L
T2=283K⋅0.285L0.250L
T2=323K
(This is also 50˚C.)

(Answer is 323k)

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?

Answers

Explanation:

Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
