heat engine x has an efficiency of 67%. heat engine y has an efficiency of 82%. which best compares these two heat engines? heat engine x moves more thermal energy from cold to warm areas than heat engine y. heat engine x releases more energy to the surroundings than heat engine y. heat engine y releases more energy to the surroundings than heat engine y. heat engine y moves more thermal energy from cold to warm areas than heat engine x.

heat engine x has an efficiency of 67%. heat engine y has an efficiency of 82%. which best compares these two heat engines? heat engine x moves more thermal energy from cold to warm areas than heat engine y. heat engine x releases more energy to the surroundings than heat engine y. heat engine y releases more energy to the surroundings than heat engine y. heat engine y moves more thermal energy from cold to warm areas than heat engine x.

Answer

Brief Explanations:

The efficiency of a heat - engine is the ratio of the work output to the heat input. A more efficient heat - engine converts a larger fraction of the input heat into work and releases less waste heat to the surroundings. Heat engine Y with 82% efficiency is more efficient than heat engine X with 67% efficiency. So heat engine X releases more energy to the surroundings as waste heat.

Answer:

Heat engine X releases more energy to the surroundings than heat engine Y.
