State one basic assumption of the kinetic theory for an ideal gas.
State one other basic assumption of the kinetic theory for an ideal gas.
State one condition under which a real gas behaves more like an ideal gas.
State one further condition under which a real gas behaves more like an ideal gas.
Place the following gases in decreasing order of ideal behaviour: ammonia, neon, nitrogen. Explain your answer.
Using the kinetic-molecular model, explain why a liquid eventually turns into a gas as the temperature is increased.
State two basic assumptions used by the kinetic theory for an ideal gas. (i) (ii)
State two conditions that make a real gas approach ideal-gas behaviour. (i) (ii)
Ethane, $\text{CH}_3\text{CH}_3$, and fluoromethane, $\text{CH}_3\text{F}$, are iso-electronic, meaning that each molecule contains the same total number of electrons. Calculate the total number of electrons in one molecule of $\text{CH}_3\text{F}$.
The boiling points of $\text{CH}_3\text{CH}_3$ and $\text{CH}_3\text{F}$ are given. Suggest explanations for why the boiling points of the two compounds are so similar.
Suggest explanations for why $\text{CH}_3\text{F}$ has the slightly higher boiling point.
