(a(i))[2]
the gas’s starting temperature.
(a(ii))[1]
the temperature rise.
(b(i))[1]
State what the symbol $\langle c^2 \rangle$ means in the expression $p = \frac{1}{3} \rho \langle c^2 \rangle$.
(b(ii))[4]
Use the expression $p = \frac{1}{3} \rho \langle c^2 \rangle$ to show that the mean kinetic energy $\langle E_K \rangle$ of the atoms in an ideal gas is $\langle E_K \rangle = \frac{3}{2} kT$. Explain any symbols that you use.
(c(i))[2]
Calculate how much gas there is.
(c(ii))[2]
Calculate the atoms’ mean kinetic energy.
(c(iii))[3]
Calculate the gas’s total internal energy.
