Suppose a heat engine pulls 337times104 j of work from the, Ask an Expert

Academics

Suppose a heat engine pulls 3.37×104 J of work from the hot reservoir and 7.52×103 J of that energy is used to perform work. How much energy is rejected by the engine? (This energy is "exhausted" to the cold reservoir.) What is the efficiency of the engine? (enter this as a unitless number between 0 and 1)
