Question

-Which term refers to water having a slightly positive end and a slightly negative end

cohesion

surface tension

polarity

hydrophilic

adhesion

- --------------------------------------------

match each one

Dissolving substance in a solution.

Reason that water is less dense as a solid and will float in water in the liquid state.

Insects can walk across water because its surface is hard to break.

Water heats up more slowly and cools more slowly than most substances.

Substance that repels water.

Force that helps move water through tiny tubes in plants.

Force that causes water to stick to glass and other objects.

Attraction between like molecules.

Water changes to a gas much slower when compared to other liquids .

capillarity

adhesion

high heat of vaporization

high specific heat

cohesion

freezing expansion

high surface tension

hydrophobic

solvent

Explanation / Answer

Water is a polar substance , which means it has slightly positive and slightly negative end. ( so the right option will be polarity. )

dissolving substances in a solution - solvent

Reason that water is less dense as a solid and will float in water in the liquid state-freezing expansion. ( that's why same volume of ice contain less weight than Same volume of water)

insects can walk across water because its surface is hard to break - high surface tension

water heats up more slowly and cools more slowly than most substances - high specific heat ( due to high specific heat it needs more temperature to heat up and retain that heat for a long time).

substances that repel water-hydrophobic

force that helps move water through tiny tubes in plants - capillarity

force that causes water stick to glass and other objects - adhesion

attraction between like molecules - cohesion ( intra molecular force that holds two molecules)
