When heat is removed, how does a gas become a liquid?
a. the particles in a liquid have less kinetic energy than the particles in gas
b. the particles in a liquid have more kinetic energy than the particles in gas.
c. the particles in a liquid have less potential energy than the particles in gas.
d. the particles in a liquid have more potential energy than the particles in gas

A.The particles in a liquid have less kinetic energy than the particles in gas

Explanation:

As we know that the kinetic energy of the gas is directly depends on the temperature of the gas

It is given by the formula

since the heat is removed from the gas then due to removal of energy the temperature of the gas molecules will decrease.

Due to this decrease in energy the molecules of gas will come closer and the force between the molecules will increase.

Now due to stronger attraction force the gas will convert into liquid

so correct answer will be

A.The particles in a liquid have less kinetic energy than the particles in gas
