When equal volumes of liquids and gases are heated through the same temperature range (at constant pressure), the gases experience a much greater increase in volume than the liquids.
What is the reason for this?
The average increase in the separation of particles in a gas is much greater than that in a liquid.
The average increase in the separation of particles in a gas is much less than that in a liquid.
The individual particles in a gas expand much more than the particles in a liquid.
The individual particles in a gas expand much less than the particles in a liquid.
