Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
A gas is heated at constant volume. According to the first law, the energy supplied by heating
increases the internal energy
is all converted to work
is lost to the surroundings
leaves ΔU unchanged
2.
In an adiabatic compression of a gas
the temperature stays constant
the internal energy decreases
no work is done
the temperature rises
3.
A gas receives 800 J by heating and does 300 J of work. ΔU is
−500 J
+1100 J
−1100 J
+500 J
4.
An ideal gas expands isothermally, doing 250 J of work. The energy supplied by heating is
0 J
250 J
−250 J
500 J
5.
2.0 mol of monatomic ideal gas is heated by 30 K at constant volume. The heat supplied is closest to (R = 8.31)
250 J
500 J
750 J
1000 J
6.
Over one complete cycle of a heat engine, the change in internal energy of the working gas is
equal to the net work done
zero
equal to the heat supplied
positive
