What happens to a gas when heat is removed?
(a.)the particles have more kinetic energy.
(b.)the particles move faster and become less compact.
(c.)the particles move slower until the matter changes into a liquid.
(d.)the particles reduce their size by at least half.

C). The particles move slower until the matter changes into a liquid.

Explanation:

When heat is removed the particles condense turning it into a liquid and further cooling will turn the gas into a solid.
