Study Notes
Kinetic Energy and Temperature
- Particles of matter possess kinetic energy, which is the energy of motion.
- As temperature rises, particles move faster, resulting in an increase in kinetic energy.
Diffusion
- Diffusion is the intermixing of particles of two different types of matter on their own.
- Particles diffuse by getting into the spaces between particles of the other substance.
- Heating a substance increases the rate of diffusion.
Particle Attraction
- Particles of matter attract each other, which is demonstrated through the human chain activity.
