Question

What does the kinetic theory state about the relationship between the speed and temperature of gas molecules?
As the temperature increases, the speed of gas molecules remains constant.
As the temperature increases, the speed of gas molecules decreases.
As the temperature increases, the speed of gas molecules increases.
As the speed of gas molecules increases, the temperature becomes constant.
As the temperature decreases, the speed of gas molecules increases.

Answer 1

As the temperature increases, the speed of gas molecules increases.

Answer 2

Answer: As the temperature increases, the speed of gas molecules increases.

Explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

$K=\frac{3RT}{2}$

K= kinetic energy

R= gas constant

T= temperature

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is more, average kinetic energy of the system is more and thus speed of the molecules will be more.
