State the key assumption in the kinetic theory of gases that gives the result that the potential energy between the atoms of an ideal gas is zero.
State what is meant by the internal energy of a substance.
Explain why an increase in the internal energy of an ideal gas is directly linked to a rise in the gas temperature.
State the change in internal energy of the gas during one full cycle PQRP.
Calculate the work done on the gas during the change from P to Q.
Some energy changes in the cycle PQRP are shown in Fig. 2.2. Complete Fig. 2.2 so that every energy change is shown.
State the change in internal energy of the gas during one full cycle PQRP.
Calculate the work done on the gas during the change from P to Q.
Some energy changes in the cycle PQRP appear in Fig. 2.2. Complete Fig. 2.2 so that all of the energy changes are shown.
