Thermal Physics

Brownian motion

random collisions between particles in the suspension and the much smaller, fast-moving particles of the gas or liquid

describe pressure

the forces exerted by particles colliding with surfaces, creating a force per unit area

describe evaporation

the escape of the more energetic particles from the surface of a liquid

everyday applications of thermal expansion

Thermometer, Thermostat

what could effect the boiling and melting point of water

If it isn’t pure water

The altitude (not at sea level)

difference between evaporation and boiling

Evaporation: Temperature decreases only at the surface, Can be at any temperature

Boiling: Constant temperature throughout the liquid, Energy input required
