Question

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on which factor?

volume
pressure
temperature
number of particles

Answer 1

Answer: The correct answer is temperature.

Step-by-step explanation:

Average kinetic energy is defined as the average of kinetic energies of all the particles in a system. It is a measure of temperature.

Mathematically,

`K=(3RT)/(2N_A)`

where,

K = average kinetic energy

R = Gas constant

`N_A` = Avogadro's number

T = temperature of the system

As, the temperature of the system increases, the average kinetic energy of the particles also increases and vice-versa.

Thus, the correct answer is temperature.

Answer 2

Answer: temperature

Step-by-step 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=(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.
