What is condensation?
Change of state from gas to liquid
What is freezing?
Change of state from liquid to solid
What is sublimation?
Change of state from solid to gas

Change of state from gas to solid
Tell me the arrangement of particles in a solid.
- Molecules are closely packed
- Strong intermolecular attraction and minimal intermolecular space
- Molecules of solids don’t move
- Hence, very difficult to change the shape of a solid by squashing it or pulling it
Tell me the arrangement of particles in a liquid.
Tell me the arrangement of particles in a gas.
What is absolute zero?
The lowest possible temperature where nothing could be colder and no heat energy remains in the substance.
At what temperature does absolute zero occur in?
0 degrees Kelvin
-273 degrees Celsius
What is brownian motion?
Tell me the eqn to find pressure in fluids.
Tell me the eqn for boyle’s law.
What is Boyle’s law?
How do you convert degrees celsius to kelvin.
