state changes Flashcards
describe the movement of particles in solids
particles vibrate around fixed points and cannot move around freely
describe the movement of particles in liquids
the particles can move past each other randomly
describe the movement of particles in gas
the particles move around very fast and move around randomly as they have lots of kinetic energy
what is state change from gas to solid
deposition
what is the state change from solid to gas
sublimation
what is the specific heat capacity
the thermal energy required to change the temperature of 1Kg of a material by 1 degree
what is the formula for change in thermal energy
= mass * specific heat capacity * change in temp
what is the specific heat capacity of water
4200
what is specific latent heat
the energy that must be transferred to change 1Kg of a substance from one state to another
what are the 2 types of specific latent heat
specific latent heat of fusion
specific latent heat of vaporisation
what is the specific latent heat of fusion
how much energy is needed to be transferred to go from solid to liquid
what is the specific latent heat of vaporisation
how much energy is needed to be transferred to go from liquid to gas
what is the formula for the thermal energy required for a change of state
mass * specific latent heat
