Question

The temperature of a fixed mass of gas increase from 100k to 400k. What will happen to its volume?

• A. It will double
• B. It will decrease to a quarter of its original volume
• C. It will increase by factor of four
• D. It will stay the same

Answer 1

The correct option is C

It will increase by factor of four

According to Charles law, its volume increases by the same amount of increase in temperature. The Charles law states that volume of given mass of a gas at constant pressure increases or decreases by $\frac{1}{273.15}$ of its volume at $0^0$C for every degree rise or fall in temperature.
