Question

Which of the following statement is true?

A) During summer, water kept in the earthen pot becomes cool because of the phenomena of boiling
B) Spreading of the virus on sneezing is example diffusion
C) There is no force of attraction between particles of gases
D) On the increasing temperature, Kinetic Energy of particles do not increase

Answer 1

The above answer is option A

Answer 2

The answer is option B.

Explanation:

A) This is false. This is because the pot has pores and the water is easily evaporated thus it remains cool.

B) This is true. Diffusion is the process when the substance moves from high concentration to low concentration. As the body has high concentration as compared to the environment. So, while sneezing it will spread due to the phenomenon of diffusion m

C) This is false. There is a negligible force of attraction or repulsion between the gases. There is very small about of force.

D) This Is false. The kinetic energy is directly proportional to temperature. So its temperature increases, then K.E increase.
