A work of 166.28 ~J is done to adiabatically compress one mole of a gas. If the increase in the temperature of the gas is 8^ C , the gas is ( R =8.314 ~J ~mol ⁻¹ ~K ⁻¹ )
Options
- Amonatomic
- Bdiatomic
- Cpolyatomic
- Dmixture of diatomic and polyatomic
Correct answer
B. diatomic
Step-by-step solution
Work done on the system, W =166.28 ~J Increase in temperature, T = T ₂- T ₁=8^ C Work done in adiabatic process, aligned & W = nR ( T ₂- T ₁ ) -1 & 166.28= 8.314 8 -1 & -1= 8.314 8 166.28 =0.4 & =1.4 aligned The gas is diatomic in nature.
