Understanding temperature and kinetic energy

Particle model of matter • Particle model and gas pressure

Key concepts

What you'll likely be quizzed about

  • Kinetic energy is the energy of motion.
  • Every particle in matter possesses kinetic energy, which varies with its mass and speed.
  • The formula for kinetic energy is KE = 1/2 mv², where m represents mass and v represents velocity.

In what way do temperature increases impact viscosity?

Click to reveal answer

Higher temperatures generally reduce viscosity, allowing liquids to flow more easily.

Key notes

Important points to keep in mind

Kinetic energy is calculated with KE = 1/2 mv².

Temperature increases kinetic energy of particles.

Higher temperature may lead to state changes.

Particle motion behavior varies with state of matter.

Thermal expansion is a direct consequence of kinetic energy increase.
