Specific Latent Heat

• When we heat a substance, we increase the temperature as we increase the energy of the particles
• When the substance changes state, the temperature stops increasing and stays constant
• Specific Latent Heat - The amount of energy required to change the state of 1kg of a substance without changing its temperature
• Takes 334 000 J of energy to melt one kilogram of ice. This is called the Specific Latent Heat of fusion
• Energy for change of state = mass x Specific Latent heat
