Section 5: Solids, Liquids and Gases
-
Brownian motion
Air knocks into the smoke and then the smoke moves in random motion which proves air moves in random motion
Boyle's Law
-
if you squeeze them into a smaller space then they'll hit the sides more often because the pressure increases
-
-
law of pressures
if you heat a gas the pressure increases because they have more kinetic energy / speed increases therefore they hit the sides more often
when temperature (kelvin unit) increases, kinetic energy increases because the speed increases

Particle theory
when they collide with something they exert a force on it and their momentum and direction change. in a container the particles collide with the wall creating an outward pressure
-
-
if you heat a gas then the particles move faster and have more kinetic energy. this means that the particles have more pressure when they hit the sides of the container.
