Question 46

A gas is at a temperature above its boiling point. The gas is then cooled so that it becomes a liquid at a temperature below its boiling point.

Which row correctly compares the gas with the liquid?

Average distance between the particlesAverage speed of the particles
Agreater in the gasgreater in the gas
Bgreater in the gassmaller in the gas
Csmaller in the gasgreater in the gas
Dsmaller in the gassmaller in the gas
A

greater in the gas | greater in the gas

B

greater in the gas | smaller in the gas

C

smaller in the gas | greater in the gas

D

smaller in the gas | smaller in the gas
