One mole of a gas absorbs 200 J of heat at constant volume. Its temperature rises from 298K To 308K. The change in internal energy is:
View answer and explanation
Correct option: A
The correct answer is A (200J) because at constant volume, all the heat absorbed goes into increasing the internal energy of the gas (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
