The statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly. That is option B.
<h3>What is Kinetic Molecular Theory (KMT)?</h3>
Kinetic Molecular Theory (KMT) is defined as the theory that describes the physical behaviour of gases.
The Kinetic Molecular Theory (KMT) include the following:
- Ideal gas molecules are constantly moving;
- They have negligible volume;
- They have negligible intermolecular forces;
- They undergo perfectly elastic collisions; and
- They have an average kinetic energy proportional to the ideal gas's absolute temperature.
Therefore, the statement that is a part of Kinetic Molecular Theory (KMT) is Molecules in a gas move rapidly.

A mixture of sand and table salt can be separated by filtration because the substances in the mixture differ in solubility. Because sand and table salt have a different ability to dissolve they can easily be separated. What can be done to separate this mixture is to add water to it and stir it thoroughly. The salt will easily dissolve in water while the sand will stay insoluble. The filtration of this mixture will result in salt being drained off with water while only the sand will remain.
A triple beam balance is used to measure mass
I take that the insects remain constant no matter what happens to the frogs (which the frogs eat presumably). So a constant food supply for the frogs is not the problem.
The line for the alligators increases over time. It their numbers increase, the frogs are in trouble. The alligators will pursue lunch with determined single mindedness and there are more of them around.
So the frogs should decrease. Their natural enemy is the alligator and alligators won't go after insects. It's not worth their time.
A is the only answer you can choose.
