Energy And Heating Flashcards
1
Q
What is the specific heat capacity
A
Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin (SI unit of specific heat capacity J kg−1 K−1).

A
Metal,aerogel
3
Q
What is heat capacity
A
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

Q
How to calculate thermal energy
A
change in thermal energy = mass × specific heat capacity × temperature change
