(a(i))[1]
State the value for absolute zero on the Celsius temperature scale.
(a(ii))[1]
State the value of absolute zero on the thermodynamic temperature scale, and include a unit in your answer.
(b(i))[1]
State what the change shown in Fig. 4.1 tells you about the gas.
(b(ii))[2]
Determine how many molecules, $N$, are in the sample of gas.
(b(iii))[1]
Use your answer in (b)(ii) to find the amount $n$ of gas in the sample.
(c)[4]
The root-mean-square (r.m.s.) speed of the molecules of the gas is $1900\,\text{m s}^{-1}$ when $pV$ is equal to $270\,\text{J}$. Determine the mass, in $u$, of one molecule of the gas, where $u$ is the unified atomic mass unit.
