Chemical formula of a water molecule

Back

H2O

Front

H2O

Back

Oxygen atom is negatively charged, Hydrogen atoms positively charged

Front

What results from an electrostatic attraction between the partial positive charge near the hydrogen atoms and the partial negative charge near the oxygen?

Back

Water polarity

Front

The tendency of water molecules to stick together is called

Back

cohesion

Front

The movement of water within the spaces of a porous material (like tree roots) due to the forces of adhesion, cohesion, and surface tension.

Back

capillary action

Front

The tendency of water molecules to stick to other substances is called?

Back

Adhesion

Front

Surface tension

Back

Water molecules generally hold together to form an invisible film on a surface.

Front

Water forms perfect, spherical droplets on a leaf due to...

Back

Polarity, cohesion and surface tension

Front

Water can work against gravity and 'climb up' the roots of plants due to...

Back

Capillary action

Front

When liquid water is confined in a tube, its surface 'sticks' to the sides of the tube and forms a meniscus.
