Water Properties

Front

What allows a water strider to skate along the top of a pond?

Back

Hydrogen bonds result in water cohesion, creating surface tension.

Front

Why does ice float on water?

Back

Ice is less dense than water because water expands when it freezes.

Front

Which part of a water molecule carries a positive charge?

Back

The hydrogen atoms.

Front

What is an example of cohesion in water?

Back

Water sticking to water.

Front

How does sweating help regulate body temperature?

Back

Water absorbs a lot of heat but only increases a little in temperature.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.

Front

What is the molecular structure of water?

Back

Water is composed of two hydrogen atoms covalently bonded to one oxygen atom (H2O).

Front

What is the significance of water's high specific heat?

Back

It allows water to absorb and store large amounts of heat, stabilizing temperatures in the environment.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion is the attraction between water molecules, while adhesion is the attraction between water molecules and other substances.

Front

Why is water considered a polar molecule?

Back

Water has a partial positive charge on one side (hydrogens) and a partial negative charge on the other side (oxygen).
