Which of the following are the most favourable conditions for liquefying a gas?
general-sciencechemistry
- ALow pressure and high temperature
- BLow pressure and low temperature
- CHigh pressure and high temperature
- DHigh pressure and low temperature
Explanation
A gas liquefies most readily below its critical temperature under compression: high pressure brings molecules close together while low temperature lowers their kinetic energy so that intermolecular forces can bind them. Hence high pressure and low temperature - D.
