A cylinder of fixed capacity of 44.8 liters contains helium gas at standard temperature and pressure. The amount of heat needed to raise the temperature of gas in the cylinder by 20.0°C will be: (Given gas constant R = 8.3 JK -1 mol -1 )
Text Solution
Verified by ExpertsThe correct answer is:
C
No of moles = 
= 2
Gas is mono atomic so 
= 60R
= 60 x 8.3
= 498J
