How to calculate change in internal energy?

Jul 13, 2022

In order to calculate the change in internal energy, you will need to know the specific heat capacity of the substance and the change in temperature. The specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. Once you have this information, you can use the equation:

ΔU = m * C * ΔT

Where:

ΔU is the change in internal energy
m is the mass of the substance
C is the specific heat capacity
ΔT is the change in temperature

For example, let’s say you have a substance with a mass of 10 grams and a specific heat capacity of 0.5. If the temperature increases by 10 degrees Celsius, the change in internal energy would be:

ΔU = 10 * 0.5 * 10
ΔU = 50

This equation can be used for any type of substance, whether it’s a solid, liquid, or gas.
