NEET Physics Thermodynamics Questions Solved


When an ideal monoatomic gas is heated at constant pressure, fraction of heat energy supplied which increases the internal energy of gas, is 

(1) 25

(2) 35

(3) 37

(4) 34

(2) For monoatomic gas

γ=CPCV=53 we know ΔQ=nCPΔT

and ΔU=nCVΔTΔUΔQ=CVCP=35

i.e. fraction of heat energy to increase the internal energy be 3/5.
