Question

The_______theory of matter states that all particles of matter are in constant motion.

Answer 1

Answer

kinetic

Explanation

Matter is anything that occupies space and has mass. There are four states of matter, solids, liquids, gases and plasma. All this consist of small molecules that are in constant random motion. This is called kinetic theory of matter.

When these molecules are in motion they may collide. No energy is gained or lost during collision. The particle/molecules move in a constant linear motion.

Answer 2

The kinetic theory of matter states that all particles of matter are in constant motion.

Further Explanation

Matter

Matter is anything that has weigh and occupies space. There are three states of matter; solid, liquid, and gases.  

Kinetic theory of Matter  

• The kinetic theory of matter states that matter is made up of many small particles such as atoms or molecules that are in continuous random motion.
• The particles making up matter possess energy which varies depending on the temperature which determines the state of matter. Particles in solid state have the lowest energy while particles in the gaseous state have the highest amount of energy.  
• Kinetic theory of matter helps explain the states of matter and why there are different states of matter.  

According to kinetic theory of matter:

1. Matter is made up many particles that are in constant movement
2. All particles in matter possess energy and depends on temperature
3. Average kinetic energy of particles is measured by the temperature of a substance
4. Change in kinetic energy of particles may cause a change in the phase of matter.
5. Particles in matter experience attractive forces between them which increases with decrease in distance between the particles. The attractive forces are called inter-molecular forces.
