Question

which of the following statement is not true regarding the characteristics of matter? a. particles of a matter are randomly moving in all directions. b. kinetic energy of the particles increases with a rise in temperature. c. kinetic energy of the particles of all matters remains the same at a particular temperature. d. particles of matter diffuse into each other on their own.
​

Answer 1

particle of matter continuously moving

Answer 2

Answer:

The statement, that the kinetic energy of the particles of all matters remains the same at a particular temperature is not true. Option c. is correct.

Explanation:

• The gas particles will hit the container more often if the kinetic energy of the gas particles is high.
• With the increase in the temperature, the kinetic energy of the gas particles increase.

It is a true statement that in a matter particles move randomly in all directions. Also, it is a true statement that in a matter particles diffuse into each other on their own. This process is known as diffusion.

But, the kinetic energy of the particles of the matter depends on the temperature as well as the mass of the particles.

So, the statement, that the kinetic energy of the particles of all matters remains the same at a particular temperature is not true.

Option c. is correct.
