Question

Which of the following represent the suitable conditions for the liquefaction of gases ?

Options

• low temperature, low pressure

• high temperature, low pressure

• low temperature, high pressure

• high temperature, high pressure

Answer 1

low temperature, high pressure

With the help of experiments it can be shown that at low temperature and high pressures, gases will liquefy. Because these factors affect the interaction force of molecules i.e. the molecules are able to establish a force of attraction between them on lowering the temperature and increasing pressure.
