according to the kinetic theory, the particles in a gas

a are in constant random motion

b are attracted to each other

c have a significant volume

d have the same kinetic energy

The answer is letter A, are in constant random motion.

Explanation:

"Kinetic Molecular Theory of Gases" shows the behavior of gases in relation to heat and temperature (thermodynamics). "Kinetic" means motion, thus it is very normal to say that the theory is about the motion of gas particles.

When it comes to "ideal gases" (gases which obey the gas law), the gas is made of of molecules or atoms, which are very small particles. These have the same amount of mass and are constantly colliding in a rapid motion. However, their collisions are "elastic," which means that, there is "no net conversion" of the molecules' or atoms' kinetic energy. This means that the "total kinetic energy "is the same or stable, but is dependent on the temperature.

Remember that the gas particles in one sample have varying speed, which means that their kinetic energy are not the same.
