| Statement 1: The temperature of gas continuously increases. |
| Statement 2: According to first law of thermodynamics dQ = dU + dW where symbols have their usual meaning. |
A) Statement-1 is false, Statement-2 is true.
B) Statement-1 is true, Statement-2 is true and statement- 2 is correct explanation for statement-1
C) Statement-1 is true, Statement-2 is true and statement- 2 is NOT correct explanation for statement-1
D) Statement-1 is true, Statement-2 is false
Correct Answer: A
Solution :
Initial condition Volume\[=76\,\,cm\times A\] Pressure = (76 + 76) dg = 152dg Final condition Volume \[=152\,cm\times A\] Pressure = 76dg \[\therefore \]\[{{P}_{1}}{{V}_{1}}={{P}_{2}}{{V}_{2}}\] \[\therefore \]Both points lie on the same isothermal line i.e. both have same T.
