Which effect occurs when heat is isothermally added during Carnot cycle expansion of a helium-filled piston engine?

💡 Explanation

When heat is added isothermally during Carnot cycle expansion, the helium absorbs the heat and performs work, because the process is designed to maintain constant temperature, leading to the volume increasing. Therefore a constant gas temperature with an exponentially increasing volume results, rather than changing temperature or approaching zero pressure which violate isothermal process constraints.
