Particle model of matter-specific latent heat

Question	Answer
Explain the cause of the flat sections on a graph of temperature against time for a substance being heated?	The energy being transferred is being used to break the intermolecular bonds rather than raising the temperature.
Define specific latent heat:	the amount of energy required to change 1 kg of a substance from one state to another without changing temperature
What is the specific latent heat of fusion?	the change between a solid and a liquid (melting or freezing)
What is the specific latent heat of vaporisation?	changing between a liquid and a gas (evaporating, condensing, boiling)
What is the equation for specific latent heat?	Image: Specific+Latent+Heat+ Copy (binary/octet-stream)
