What is the difference between sensible and latent heat?

What will be an ideal response?


There are two forms of heat. One is called sensible because as it changes a change in temperature can be sensed or measured. The other form of heat is called latent. Latent heat is the heat required to change matter from one state to another, and it does not result in a temperature change. For example, if a pot containing water is heated on a stove, the water picks up heat from the burner and the water's temperature increases. The more heat put into the water the higher its temperature until it begins to boil. Once the water reaches 212°F (100°C), its temperature stops rising. As long as the pot is on the burner, heat is being put into the water, but there is no increase in sensible heat. The heat is all going into the latent heat required to change the water from the liquid state to a gaseous state.
