PHXI12:THERMODYNAMICS

371245 In a given process of an ideal gas, \(dW = 0,\,\,dQ < 0\) then for the gas

1 The temperature will decrease
2 The volume will increase
3 The pressure will remain constant
4 The temperature will increase
PHXI12:THERMODYNAMICS

371246 Assertion :
First law of thermodynamics is a restatement of the principle of conservation of energy
Reason :
Thermal energy is a thermodynamic variable.

1 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
PHXI12:THERMODYNAMICS

371247 Assertion :
The heat supplied to a system is not always equal to the sum of increase in its internal energy and work done by the system.
Reason :
When a system changes from one thermal equilibrium state to another, some heat is absorbed by it.

1 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
