solute

what is being dissolved

solvent

what is doing the dissolving

solution

a homogenous mixture of two or more substances

cohesion

water molecules sticking to each other

surface tension

thin film on top of water formed by cohesion

adhesion

attraction between two different substances

cohesion + adhesion = ?

capillary action

capillary action

water molecules tow each other along when in a thin tube

heat of vaporization

The amount of energy required to turn 1g of a substance from a liquid to a gas. Water has a HIGH heat of vaporization.

in order for water to evaporate, ______________ must be broken.

hydrogen bonds

specific heat

the amount of heat required to raise or lower 1g of a substance 1 degree Celsius. Water has a HIGH specific heat.

Water can absorb lots of heat energy with little change in actual temperature. True or false?

True! Water resists temperature change.

Ice is denser as a solid than it is as a liquid. True or false?

False. Ice expands upon freezing.
