When 3mole of an idela gas expand reversibly and isothermally five times its initial volume `6kJ` heat flow into it. What must be the temperature of the gas?

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the Given Data
- Number of moles (n) = 3 moles
- Heat flow into the gas (Q) = 6 kJ = 6000 J (since 1 kJ = 1000 J)
- Initial volume (V1) = V
- Final volume (V2) = 5V (since it expands 5 times its initial volume)
