What is convection?

a Transfer of heat through objects touching the source

b Transfer of heat through direct physical contact

c Transfer of heat through electromagnetic waves

d Transfer of heat through the movement of particles

Answers

Answer 1

Answer:

d transfer of heat through the movement of particles

Answer 2

The correct answer is option d: Transfer of heat through the movement of particles. Convection is a mode of heat transfer that occurs through the movement of particles.

Convection is the transfer of heat through the movement of particles in a fluid, such as a gas or liquid. Option (d) is the correct answer. Convection occurs when a temperature difference exists within the fluid, causing the hotter particles to become less dense and rise while the cooler particles sink. This movement creates a circulation pattern known as convection currents. Convection is a significant mechanism for heat transfer in various natural and man-made systems. For example, when a pot of water is heated on a stove, the bottom of the pot gets hot, causing the water near the bottom to heat up and expand. This hot water rises to the top, transferring heat to the surrounding cooler water. As a result, the water circulates in a convection current, leading to a more uniform distribution of heat. Convection is also responsible for phenomena like ocean currents, atmospheric circulation, and even the formation of thunderstorms. It plays a crucial role in distributing heat within the Earth's atmosphere and oceans, impacting weather patterns and climate.

What effect does heat have on a chemical reaction?

Answers

Answer:

Particles can only react when they collide. If you heat a substance, the particles move faster and so collide more frequently. That will speed up the rate of reaction. ... The rate of reaction will probably have doubled for that increase in temperature - in other words, an increase of about 100%.

b.36g/mL

c.3g/mLd.18g/mL


Im begging someone to help, Ill mark brainlist!!!

Answers

Answer:

a. 0.33 g/mL

Explanation:

We already know what the mass is (9 grams) so we have to find the volume of the cube next.

Volume = lwh

             =(3)(3(3)

             = 27

To find density, you have to find mass/volume

density = mass /volume

density = 9 g /27 mL             (cm 3 and mL are basically the same thing)

            = 0.33 g/mL

0.33 g/ml is the correct answer

The chemical formula for hydrogen peroxide is H₂O₂. The total number of atoms in 1 molecule of hydrogen peroxide is four atoms. Two atoms of hydrogen and two atoms of oxygen.

What is hydrogen peroxide ?

Chemically, hydrogen peroxide has the formula H₂O₂. It is a somewhat more viscous liquid than water, and very pale blue when it is pure. For consumer use, it is typically diluted in water and used as an oxidant, bleaching agent, and antiseptic. For industrial use, larger concentrations are utilized.

Hair bleaching, surface cleaning, and tool disinfection are all done using hydrogen peroxide. It is also utilized in gardening and dental hygiene.

Two hydrogen and two oxygen atoms make up one molecule of H₂O₂. Therefore, two molecules of H2O2 contain four hydrogen and four oxygen atoms each. Two hydrogen atoms and one oxygen atom make up a water molecule.

Thus,  The total number of atoms in 1 molecule of hydrogen peroxide is four atoms.
