Which outcome manifests when a Carnot heat engine cycle is modified to remove an isothermal process?

💡 Explanation

Removing the isothermal process prevents maintaining constant temperatures; therefore, less heat converts to work, reducing maximum theoretical efficiency because efficiency requires reversible heat transfer, rather than irreversible temperature changes at constant volumes.
