Heat and Thermal ExpansionHard
Question
The graph below shows V -P curve for three processes
Chose the correct statement (s)
Chose the correct statement (s)
Options
A.Work done is maximum in process 1.
B.Temperature must increase in process 2 & 3.
C.Heat must be increase in process 2 & 3.
D.If final volume of gas in process 1, 2
Solution
Area under P - V curve and volume axis represent work.
Internal energy in 1 increase(expansion at constant pressure)
In process 2 and 3 internal energy may decrease depending on the process.
Since final pressure of 1, 2 & 3 ar different, final temprature must also be different.
