What is kinetic energy?

• Kinetic energy is the energy associated with an object's temperature.
• Kinetic energy is the energy of an object in motion.
• Kinetic energy is the energy stored in an object at rest.
• Kinetic energy is the energy released during a chemical reaction.

How are particles involved in the flow of heat?

• Particles absorb heat without transferring it.
• Heat flows only through liquids and gases, not solids.
• Particles do not interact during heat transfer.
• Particles transfer energy through collisions and movement, facilitating the flow of heat.

How do you know once a substance has reached equilibrium?

• The temperature of the substance changes significantly.
• The pressure of the system fluctuates constantly.
• The reaction stops completely and no further changes occur.
• The concentrations of reactants and products remain constant.

In what direction does heat flow?

• Heat flows from hot to cold.
• Heat does not flow at all.
• Heat flows in all directions equally.
• Heat flows from cold to hot.

What happens when photons are absorbed in radiant heat?

• Photons are converted into heat without affecting the material.
• Photons are reflected back into space, keeping the material cool.
• Photons cause the material to emit light instead of heat.
• Photons transfer their energy to the material, increasing its temperature.
