An ideal gas initially at pressure 1 bar is being compressed from 30 m3 to 10 m3 volume and its temperature decreases from 320 K to 280 K, then find the value of final pressure of the gas. [AIIMS 2019]
Given, initial pressure of ideal gas,
p1 = 1 bar =
Initital volume, V1 = 30 m3
Final volume, V2 = 10 m3
Initial temperature, T1 = 320 K
Final temperature, T2 = 280 K
Final pressure of gas, p2 = ?
From ideal gas equation,
p2 = 2.625 bar
