The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter.

The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.

Energy and State of Matter A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy).

This graph shows a decrease in pressure as average kinetic energy increases. From KMT theory we know that pressure will increase in a fixed volume as the average kinetic energy increases.

As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.

gas

therefore, more kinetic energy! An object has the MOST kinetic energy when it’s movement is the GREATEST.

What Are Examples of Potential and Kinetic Energy?

• 1) Planets. The movement of planets around the sun and other stars in the galaxy is kinetic energy at work.
• 2) Rubber Bands. Rubber bands can be classified as both potential and kinetic energy, depending on the state of the band.
• 3) Rivers.
• 4) Specific Variations.
