2.An ideal gas is in a container of volume $2.5\times10^4\,cm^3$. The pressure of the gas is $3.0\times10^4\,Pa$ at a temperature of $127^{\circ}C$
1.Determine how many molecules there are in the gas.
2.Estimate the total kinetic energy of the gas molecules.
3.The gas is heated at a constant rate to reach a temperature of $800K$. The change in the volume of the container is negligible.
1.Determine the pressure of the gas at $800K$.
2.On the graph below, sketch how the mean square speed $\bar{c^2}$ of the gas molecules varies with temperature $T$during the heating process.
(there is no need to add values on the axis)
