When a gas filled in a closed vessel is heated by raising the temperature by 1 ° C , its pressure increases by 0 . 4 % The initial temperature of the gas is _____ K .

Correct answer

0

Step-by-step solution

From ideal gas equation, P V = n R T , where, n is amount of substance, R is ideal gas constant and V is volume. In closed vessel volume remains constant. So, d P P × 100 = d T T × 100 0 . 4 = 1 T × 100 ⇒ T = 250   K
