Q
What is specific heat capacity?
A
The energy required to raise the temp of 1kg of a substance by 1°c
2
Q
What is the specific heat capacity equation?
A
Change in thermal energy ÷ (mass × temp change)
3
Q
How can energy loss be reduced in specific heat capacity experiments?
A
Insulation and using a lid
4
Q
What is percentage difference used for?
A
Comparing experimental and theoretical results
5
Q
What is specific latent heat?
A
Energy required to change the state of 1kg of a substance without temp change
6
Q
What is the latent heat equation?
A
Specific latent heat = energy ÷ mass
7
Q
What happens to internal energy during melting or boiling?
A
It decreases while temp stays constant
8
Q
How are gas pressure and temp related?
A
Increasing temp increases pressure if volume is constant
