An ideal gas expands from volume V₁ to V₂. This may be achieved by either of the three processes: isobaric, isothermal & adiabatic. Let $Δ U$ be the change in internal energy of the gas. Q be the quantity of heat added to the system and W be the work done by the system on the gas. Identify which of the following statements is correct.

Detailed Solution

In adiabatic, work done is positive, so change in internal energy is negative.

In isobaric process, the area under the curve (work done by gas) is maximum.

In isothermal process, the internal energy remains same.
