An ideal gas occupies a volume of 2 m3

Asked by admin @ 17/08/2021 in Physics viewed by 304 People

An ideal gas occupies a volume of 2m3 at a pressure of 3106 pa. The energy of the gas is :

Answered by admin @ 17/08/2021

volume of gas, V = 2m³

pressure of gas, P = 3 × 10^6 Pa

[ 1Pa = 1N/m² ]

so, pressure of gas, P = 3 × 10^6 N/m²

use formula, $E=\frac{3}{2}PV$

where E denotes energy of gas.

= 3/2 × 3 × 10^6 × 2 J

= 3 × 3 × 10^6 J

= 9 × 10^6 J

hence, energy of gas is 9 × 10^6 J
