500 joule of heat was supplied to a system at constant volume. It resulted in the increase of temperature of the system from `20^(@)C` to `25^(@)C`. What is the change in internal energy of the system ?

Explanation

To solve the problem, we need to determine the change in internal energy (ΔU) of a system when heat is supplied at constant volume. Here’s the step-by-step solution:

### Step 1: Understand the Given Information
- Heat supplied (Q) = 500 joules
- Initial temperature (T1) = 20°C
- Final temperature (T2) = 25°C
- The process occurs at constant volume.
