Solids have the strongest IMF's for a ______

Difference between boiling point, and normal boiling point: Boiling point: When vapor pressure = atmospheric pressure Normal boiling Point: Temperature at which the vapor pressure is equal to 101.3 KPA cr² Temp at which liquids (of the liquid CR boil at standard Pressure forces break ______

How boiling is a cooling process: As liquids vaporize, they absorb large amounts of ______ Cooling it.

What happens when a substance reaches its melting point? The state changes to a liquid, and there is an increase In the kinetic ______. The ______ causes the solid molecules to vibrate faster and break forces that held them together.

How can ______ boil at room temperature? A Vacuum pump is used to lower the external pressure until it equals vapor pressure of the ______.

If the average temperature of a beaker is 55°C, do all the particles have the same amount of ______?

Define ______ pressure. Why must it be measured in a closed container?

How does evaporation lower the temperature of a liquid? When evaporation occurs, particles with the highest kinetic energies ______

The effect that increasing temperature has on the vapour pressure of a liquid: Temperature increases kinetic energy of molecules, allowing more to ______, increasing vapour pressure.

Why does the boiling point of a liquid vary with atmospheric pressure? The greater the pressure, the more energy required for liquids to boil, and the higher the boiling ______
