When the temperature of a gas decreases at a constant volume, its

• pressure decreases

• mass increases

• particles speed up

The greater the pressure of gas particles in a container, the

• lower the speed

• greater the speed

• speed stays constant

The surface of water can act like skin due to a property of liquids called

• sublimation

• viscosity

• surface tension

• condensation

The opposite of vaporization is called

• sublimation

• evaporation

• condensation
