ANALYZE Explain why the liquid in a thermometer expands as temperature increases. How is this related to the kinetic energy of the particles that make up the liquid?

The liquid expands as its temperature increases like stated. This is the same as saying that it occupies more space as temperature increases. Therefore it 'uses up' more of the space inside the thermometer as the temperature increases. the relation with kinetic energy is through the kinetic energy being used as it flows and expands, because of the heat, and mercurys relationship with heat. sorry if that's off :/
