New cards
specific heat capacity
the amount of energy needed to raise the temperature of 1kg of the substance by 1 degree
2
New cards
internal energy
the energy stored in a system by the particles that make up the system
3
New cards
what increases internal energy
heating
4
New cards
what decreases internal energy
cooling
5
New cards
what is always conserved in state changes
mass
6
New cards
specific heat capacity of water
4200 J/kg C
7
New cards
the more spaced out particles are
the more potential energy they have
8
New cards
why do solids have the least potential energy
they are the closest together
9
New cards
the lower the specific heat capacity
the less energy needed to raise the temperature
10
New cards
the higher the specific heat capacity
the more energy is needed to raise the temperature
11
New cards
latent heat of fusion
the amount of energy needed to change a substance from solid to liquid
12
New cards
latent heat of vaporisation
the amount of energy needed to change a substance from liquid to vapour
13
New cards
specific latent heat
the amount of energy needed to change the state of 1kg of the substance with no temperature change
