Question 1

Hydrogen Bonding

Answer 1

When a negative pole of one molecule is bonded to a positive pole of another molecule

Question 2

Cohesion

Answer 2

When the hydrogen bonds hold the structure together (beads of water)

Question 3

Adhesion

Answer 3

The clinging of one substance to another substance (water strider walking on water)

Question 4

Calorie

Answer 4

The amount of heat it takes to raise the temperature of 1g of water 1C

Question 5

Specific Heat

Answer 5

The amount of heat that must be absorbed or lost for 1g of that substance to change temperature by 1*C

Question 6

Water’s Specific Heat

Answer 6

Heat is used up to break/form hydrogen bonds before it causes that water molecules to move faster or slower
-Allows water to store heat without changing temperature. Causes milder coastal climates and and a favorable marine environment

Question 7

Heat of Vaporization

Answer 7

Quantity of heat needed for a liquid to be converted to a gaseous state
Moderates the Earths climate, accounts for severity of steam burns

Question 8

Solid Water less Dense than Liquid

Answer 8

When water molecules are converted from the liquid to solid state, they become locked in a crystalline lattice in which the hydrogen bonds keep the water molecules at length from eachother. Causes a 10 percent reduction in density.
This allows marine life to live year round

Question 9

Solvent

Answer 9

Dissolving agent of a solution

Question 10

Solution

Answer 10

A liquid that is homogenous mixture of two or more substances

Question 11

Solute

Answer 11

Substance that is dissolved

Question 12

Hydrophobic

Answer 12

Repel Water

Question 13

Hydrophylic

Answer 13

Affinity to Water
