Question

when a gas filled in a close vessel is heated through 1C, its pressure is increased by 0.4 % The initial temperature of the gas was

1. 250 K
2. 2500 K
3. 250 C
4. 25 C

Answer 1

As we know from ideal gas equation Pressure is directly proportional to temperature at constant volume. So, increase in pressure is directly proportional to increase in temperature at constant volume. Thus, we can write as
