The pressure exerted by a certain mass of enclosed gas at 300 K is 5 �

1.	The pressure exerted by a certain mass of enclosed gas at 300 K is 5 × 104 Pa. What will be the pressure exerted by the gas at 600 K if the volume of the gas is kept constant ?
Answer» Here, P ∝ T ∴ \(\frac{P_2}{P_1}\) = \(\frac{T_2}{T_1}\) = \(\frac{600}{300}\) = 2 ∴ P = 2P₁ = 2 × 5 × 10⁴ Pa = 10⁵ Pa is the required pressure.

Answer»

Here, P ∝ T

∴ \(\frac{P_2}{P_1}\) = \(\frac{T_2}{T_1}\) = \(\frac{600}{300}\) = 2

∴ P = 2P₁ = 2 × 5 × 10⁴ Pa = 10⁵ Pa is the required pressure.
