Key Takeaways:

Boyle's Law
Pressure is inversely proportional to Volume
(Temperature at constant)

Gay Lussac's Law
Temperature is directly proportional to Pressure
(Volume at constant)

At absolute zero (0K, 273.15 C), pressure = 0 atm, particles are stationary

Light particles move faster than heavier ones (ceteris paribus),
thus having more kinetic energy.

Brownian Motion:
The random motion/movement of particles suspended in a fluid (liquid or gas) resulting from collisions with fast moving molecules in the fluid. It corresponds to the Kinetic Theory of Matter that states all matter is made up of a large amount of tiny particles in continual, random motion, which is also an assumption for ideal gases.
