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
cohesion
surface tension
polarity

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)
