Question

Boyle’s and Charle’s law are obeyed by low density gases only. True or False?

(a) True

(b) False

The question was posed to me in homework.

The above asked question is from Thermal Properties of Matter topic in portion Thermal Properties of Matter of Physics – Class 11

Answer 1

Correct answer is (a) True

To explain I would say: Boyle’s and Charle’s law are used to arrive at the ideal gas law. And the ideal gas law is based on the assumptions of kinetic theory of gases, which are only valid for low density gases. For eg: the assumption that molecules exert no forces on each other can only be considered for low density.
