Question 117 of 190
Statement - I : When amount of an ideal gas undergoes adiabatic change from state to state , then work done is , where and universal gas constant.
Statement - II : In the above case, when work is done on the gas, the temperature of the gas would rise.
Show answer and solution
Answer: (A) Both statement-I and statement-II are true.
The work done in an adiabatic process is given by,
statement I is true.
For adiabatic process . From the first law of thermodynamics,
If work is done on the gas, i.e. work is negative
is positive.
The temperature will increase. Hence, statement II is also true.
