Which outcome occurs when an irreversible heat engine operates with significant internal friction?

💡 Explanation

When irreversible processes, such as internal friction, occur in a heat engine, energy is dissipated as heat due to the friction, increasing the system's entropy and reducing the amount of work output compared to the heat input. Therefore, reduced engine efficiency and increased entropy result, rather than increasing power output, achieving reversibility, or operating at Carnot efficiency, which would require frictionless and isothermal conditions.
