NEET Physics Thermodynamics Questions Solved


The volume of a gas is reduced adiabatically to 14 of its volume at 27°C, if the value of γ = 1.4, then the new temperature will be - 

(1) 350 × 40.4 K

(2) 300 × 40.4 K

(3) 150 × 40.4 K

(4) None of these

(2) For adiabatic change TVγ1 = constant

T2T1=V1V2γ1T2=V1V2γ1×T1

T2=VV/41.41×300=300×(4)0.4K
