Specific Latent Heat Quiz

What is the concept of specific latent heat?

• A measure of the average internal energy of all the particles in a substance

• The energy required to change one kilo of a particular substance from one state to another without changing its temperature

• The energy released when a substance changes between a liquid and a gas

• The energy change when a substance changes between a solid and a liquid

What happens to the temperature of a substance during a change in states?

• It fluctuates randomly

• It increases continuously

• It decreases continuously

• It remains constant

What is the specific latent heat of fusion?

• The energy released when a substance changes from a liquid to a gas

• The energy required to change a substance from a liquid to a gas

• The energy released when a substance changes from a gas to a liquid

• The energy required to change a substance from a solid to a liquid

What is the specific latent heat of vaporization?

• The energy required to change a substance from a solid to a liquid

• The energy required to change a substance from a liquid to a gas

• The energy released when a substance changes from a liquid to a gas

What is the equation for specific latent heat?

• Energy = mass x specific latent heat

• Energy = mass x temperature

• Energy = mass x specific heat capacity

• Energy = mass x heat of fusion
