What is sensible heat?

• Heat energy that leads to a change in state without an increase in temperature

• Heat energy that leads to an increase in temperature without a change in state

• Heat energy that is absorbed when substances melt or boil

• Heat energy that is released or absorbed in the atmosphere

What is latent heat?

• Heat energy that leads to a change in state without an increase in temperature

• Heat energy that leads to an increase in temperature without a change in state

• Heat energy that is absorbed when substances melt or boil

• Heat energy that is released or absorbed in the atmosphere

What is the difference between latent heat and sensible heat?

• Latent heat is related to changes in temperature, while sensible heat is related to changes in state
