Question

Select all that are true.

Group of answer choices

A heat engine will theoretically be more efficient when it is colder out- when there is a bigger difference in temperature between the hot and cold reservoirs.

A heat pump has a higher maximum ideal coefficient of performance when the temperature outside is closer to the temperature inside your house.

It is likely that one day there will be no temperature difference between any two points in the universe and it will die a "heat death."

A hybrid electric car can use electricity as well as burn gas, and can charge a battery by converting kinetic energy to chemical energy (recharging) during the braking process.

Answer 1

TRue------A heat engine will theoretically be more efficient when it is colder out- when there is a bigger difference in temperature between the hot and cold reservoirs as because sink at low temperature to source provides max. efficiency.

TRUE---- It is likely that one day there will be no temperature difference between any two points in the universe and it will die a "heat death." as because universe is expanding one day there will be very low temperature causing heat death.

TRue---A hybrid electric car can use electricity as well as burn gas, and can charge a battery by converting kinetic energy to chemical energy (recharging) during the braking process. these are special type of cars which can work on both and can charge during regenarative braking.
