A student claims that if an ideal gas is heated from $100\,^{\circ}\text{C}$ to $200\,^{\circ}\text{C}$, its internal energy becomes twice as large.
(a(i))[2]
State the meaning of internal energy.
(a(ii))[3]
Using one of the assumptions of the kinetic theory of gases together with your response in (i), deduce the meaning of the internal energy of an ideal gas.
(b)[2]
State and explain whether the student’s suggestion is right.
