Particle model of matter 2 Flashcards
what is specific latent heat?
the energy required to change 1kg of a substance
without changing the temp.
what is specific heat capacity?
the energy needed to increase the temp. of 1kg of a substance by 1 degree
condensation
gas to liquid
particles condense into a liquid due to the forces between particles increasing
where does latent heat go?
rather than transferring the energy to a kinetic store of substances particles, the energy is absorbed and used to create or weaken bonds.
when does a liquid boil?
when it has enough energy to completely escape the forces between them
What term is used to describe the hidden energy when a solid becomes a liquid or a liquid becomes a solid?
latent heat of fusion
What happens to the energy supplied during a change of state at both the melting and boiling points?
kinetic energy remains constant while potential energy increases
