At the same conditions of pressure, volume and
temperature, work done is maximum for which
gas if all gases have equal masses?
temperature, work done is maximum for which
gas if all gases have equal masses?
View answer and explanation
Correct option: A
Option A (NH3) is correct because, with equal masses, the gas with the smallest molar mass (NH3) will have the most moles, leading to maximum work done.

An ideal gas is allowed to expand both reversibly and irreversibly in an isolated system. If is the initial temperature and is the final temperature, which of the following statements is correct?
For which of the process, ∆S is negative?
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
