A certain amount of heat energy is supplied to a mono atomic ideal gas which expands at constant pressure. What fraction of heat energy is converted into work.

View answer and explanation

Correct option: C

\frac{2}{5}

Option C (2/5) is correct because for a monoatomic gas expanding at constant pressure, 2/5 of the heat energy is converted into work, based on the first law of thermodynamics.
