## Latent Heat

Latent Heat. Thermal Physics Lesson 2. Learning Objectives. Define specific latent heat. Perform calculations using ∆Q=ml. Describe how specific latent heat of fusion/vaporisation can be measured in the lab. Explain why energy is needed to evaporate a liquid/melt a solid. Safety.

## Latent Heat

Latent Heat. Solid. Gas. Phases of Matter. The properties of solids, liquids, and gases differ. How does matter change state?. Liquid. Watched Pot. You want to cook a pot of potatoes in boiling water. To use energy most efficiently, you should

## Latent Heat

Latent Heat. Physics Montwood High School R. Casao. Change of State. Matter exists in 3 states: Solid Liquid Gas. Consider water:. vaporization (takes place at boiling point). fusion (at melting point). ice. water. steam. solidification. condensation. at freezing point.

## Latent Heat

Latent Heat. Changes in State. Energy and States of Matter. The energy and organization of the particles in a sample of matter determine the physical state, or phase , of the matter: solid, liquid, or gas. Energy and States of Matter.

## Latent Heat

Latent Heat. When a solid melts or a liquid boils, energy must be added but the temperature remains constant! (This can be explained by considering that it takes energy to break the bonds holding the material together.)
