Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

dCv/dT is 0 for real gas and vanderwaal gas..so 4th statement is correct
heat capacity may be negative,positive and infinitive...So 3rd statement is also correct
During phase change,temperature doesn't changes as the heat which is absorbed is used only to separate the molecules during phase change,it is not used to increase in KE of molecules so temp remains same....So 2nd statement is also correct
The heat given off or absorbed when a reaction is run at constant volume is equal to the change in the internal energy of the system. ... The heat given off or absorbed when a reaction is run at constant pressure is equal to the change in the enthalpy of the system. So depend on experimental condition heat is either internal energy or enthalpy...Hence 1st statement is also correct
please accept the answer if you got it😊
all are correct
booklet me ans glt h shayad
yes reshav
book me option b diya h
no it will be d
check previous query too reshav
