How does the change of state in matter occur?

Occurs when the particles gain energy or lose energy depending on the liquid

What is kinetic particle model of matter?

Tiny particles that make up matter are always in continous random motion.

Define the term “Absolute Zero”.

The lowest point of a temperature where the particles have the least amount of kinetic energy.

Temperature of “Absolute Zero”.

-273°C.

Define the term “Brownian Motion”.

Random movement of microscopic particles in a fluid due to collisions by the molecules of the fluid.

Formula for “Boyle’s Law”.

P₁V₁ = P₂V₂.
