Which statement is part of the kinetic molecular theory? a. gas particles are in constant motion. b. gas particles attract each other. c. gas particles lose their energy during collisions. d. gas particles stick to the walls of their container.

The correct answer is Option A.

Explanation: Kinetic molecular theory is used to study the behavior of gases. Some of the postulates of this theory are:

From the above postulates, it is clear that statement A is correct for kinetic molecular theory.

“A. Gas particles are in constant motion” is a part of the Kinetic Molecular Theory

In the Kinetic Molecular Theory, gas particles do not

•attract each other

•lose energy during collisions

•stick to the walls of their container.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
