At a constant volume the specific heat of a gas is 0.075 and its molecular weight is 40 . The gas is:
Options
- AMonoatomic
- BDiatomic
- CTriatomic
- DNone of these
Correct answer
A. Monoatomic
Step-by-step solution
aligned & q= c m & C_ v =q m &=0.075 40 &=3.0 cal & C_ P -C_ v =R & C_ P =C_ V +R &=3+2=5 & C_ P C_ V = 5 3 =1.66 aligned Monoatomic gas
