Question 2

What is Heat Capacity?

Answer 2

• Heat capacity (C) measures the amount of energy needed to raise the temperature of a material.

Question 3

How can the internal energy (∆E) be calculated?

Answer 3

• With a constant volume the change in internal energy (∆E) can be calculated by knowing the heat evolved or absorbed by the system, since the amount of work
done is zero.
