igniting a furnace
activating a thermostat
6)which best describes why heat pumps are reversible?
they can heat and cool an indoor space.
they involve a metal expanding or contracting against another.
they combust and can also add coolant.
they allow a piston to move up and down.
7)the thermal energy in a heat engine is used to move a piston. which best describes why this is possible?
the increase in thermal energy results in an increase in pressure.
the decrease in thermal energy results in an increase in pressure.
the increase in thermal energy results in a decrease in pressure.
