State the fundamental assumption in the kinetic theory of gases that makes the potential energy between the atoms of an ideal gas zero.
State what the term internal energy means for a substance.
Explain why an increase in the internal energy of an ideal gas is directly linked to an increase in the gas temperature.
State the change in internal energy of the gas during one complete cycle PQRP.
Calculate the work done on the gas for the change from P to Q.
Fig. 2.2 shows some of the energy changes during the cycle PQRP. Complete Fig. 2.2 so that every energy change is shown.
State the change in internal energy of the gas during one complete cycle $P \rightarrow Q \rightarrow R \rightarrow P$.
Calculate the work done on the gas during the change from $P$ to $Q$.
Fig. 2.2 shows some of the energy changes during the cycle $P \rightarrow Q \rightarrow R \rightarrow P$. Complete Fig. 2.2 so that all of the energy changes are shown.
