Thermal Physics- Equations

Question 0

The link between initial and final temperature and volume (Charle’s law)

Answer 0

V1/T1 = V2/T2

Question 1

The link between initial and final pressure and volume (Boyle’s law)

Answer 1

P1 x V1 = P2 x V2

Question 2

The link between initial and final pressure and temperature (pressure law)

Answer 2

P1/T1 = P2/T2

Question 3

The link between initial and final temperature, volume and pressure (all Gas laws)

Answer 3

P1V1/T1 = P2V2/T2

Question 4

For specific heat capacity (the amount of energy needed to raise the temperature of 1kg of the substance by 1 degree Celsius)

Answer 4

Q=mc

Question 5

For thermal capacity (the amount of heat energy needed to raise the temperature of any mass by 1 degree Celsius)

Answer 5

Thermal capacity= m x c

Question 6

For Specific latent heat (the amount of heat energy required to change state - fusion=solid to liquid vapourisation=liquid to gas)

Answer 6

Latent heat = Q/m
