Terms in this set (20)
heat flowing by means of conduction When a steel block at 100 ºC is placed on top of a copper block at 20 ºC,
the thermal energy of the copper begins to increase.
What is the source of this increase in energy?
Energy is transferred to the gas from the heat source, A heated gas expands, raising a piston. Describe the energy exchanges of
and to the raised piston from the gas. this process:
150 J A proposed ideal heat engine would run with a high temperature reservoir
at 800 kelvin and a low temperature reservoir at 300 kelvin. When the
engine is running, it extracts 400 joules of energy from the hot reservoir
and does 250 joules of work each minute.
How much energy is expelled to the low temperature reservoir each
minute?
