How are boiling and evaporating different?
They both are processes that change a liquid to a gas.
Boiling requires heat to be added so the particles rapidly change to a gas.
Evaporating requires heat to be added so the particles rapidly change to a gas.
Particles begin to move faster if they have an increase in
speed
size of particle
thermal energy
thermometer
Which of the following describes the process of freezing?

Freezing occurs when the temperature drops enough a gas turns into a solid.
Freezing occurs when the particles in a liquid slow down and take fixed positions.
Freezing occurs when the temperature of a substance drops to 0 degrees Celsius.
