Spesific Heat Capacity/ Latent heat Flashcards
1
Q
What is the formula for Specific Heat Capacity
A
E= mc🔺T
E= energy m= mass c= specific heat capacity 🔺T = change in temperature
2
Q
Rearrange the formula for specific heat capacity(SHC) to find SHC
A
c=E/(m*🔺T)
3
Q
define SHC
A
The amount of energy needed to change 1Kg of a substance by 1°C
4
Q
What are the units
A
J/Kg°C
5
Q
What’s an equation for energy
A
E= VIt
6
Q
What’s the formula for SLH (speditiv latent heat)
A
E = ml
7
Q
Define SLH of fusion
A
The energy required to change 1Kg of a solid substance into a liquid of the same substance.
8
Q
Define SLH of vaporisation
A
The energy required to change 1Kg of a liquid substance into a gas of the same substance.
9
Q
Why is SLH of vaporisation so much bigger than SLH of fusion.
A
Because the bonds have to completely broken and gas particles move at a much higher velocity.
