Properties of Water- USBT

Surface Tension

caused by water molecules being attracted to one another (cohesion)

Cohesion

water molecules sticking together

Adhesion

water molecules sticking to other things

Capillary Action

allows water molecules to move through things (adhesion) like tiny tubes in roots of plants.

Water

is the universal solvent

Specific Heat

the amount of heat needed to raise the temperature of a 1kg sample by 1 degree Celsius

Polarity

one end of the molecule has a positive charge and the other end has a negative charge

Density

The decrease in this is demonstrated in ice compared to liquid, allowing water molecules to expand and float.

Expansion

Water molecules spread apart or space out when water becomes ice, causing ice to float.

Surface Tension

The property of water that allows small organisms like spiders to walk on water.

Universal Solvent

water can dissolve many substances.

Hydrogen bond

The weak bond between water molecules that holds one water molecule to another.
