P3: SHC AND SLH Flashcards
1
Q
Define internal energy
A
-a measure of how much energy a substance has
-it is made up of two different stores of energy: kinetic and potential
2
Q
Define specific heat capacity
A
the amount of energy required to raise 1kg of a substance by 1°C
3
Q
SHC equation
A
SHC (J/kg°C) = energy (J) / mass (kg) x temp change (°C) (C = E/mθ)
4
Q
Define specific latent heat?
A
the amount of energy required to change the state of a substance with no temp change
5
Q
SLH equation
A
SLH (J/kg) = energy (J) / mass (kg) (L = E/m)
