Question

Which of the following is an assumption of Kinetic theory of matter?

• A. Molecules are in a state of continuous motion and possess kinetic energy.
• B. The kinetic energy of molecules increases with increase in temperature.
• C. The molecules of matter always attract each other due to forces of cohesion and adhesion.
• D. All of the above

Answer 1

The correct option is D All of the above

The following are the assumptions made regarding the motion of molecules in matter:

1. Molecules are in a state of continuous motion and possess kinetic energy.

2. The kinetic energy of molecules increases with an increase in temperature and decreases with a decreases in temperature.

3. The molecules of matter always attract each other due to the intermolecular force of attraction.

4. Molecules of matter have space in between them.

5. If the intermolecular space is small, intermolecular force of attraction increases.
