When 1 mole of gas is heated at constant volume. Temperature is raised from 298 to 308 K. Heat supplied to the gas is 500 J. Then which statement is correct?
View answer and explanation
Correct option: B
q=∆U=500 J,W=0
The correct answer is B (q=∆U=500 J,W=0) because at constant volume, no work is done (W=0), and all the heat supplied goes into increasing the internal energy (q=∆U).

The work done by a weightless piston in causing an expansion ∆V (at constant temperature), when the opposing pressure, P is variable, is given by:
Assertion :- At constant pressure of the change work done is negative.
Reason :- During phase transition work done is always negative. For the reaction, at . Hence, is
