|
Term
|
Definition
| Related to cohesion, measure of how difficult it is to stretch or break the surface of a liquid. Water has a higher tension than most liquids |
|

|
|
Term
|
Definition
| A measure of the total amount of kinetic energy due to molecular motion is in a body of matter |
|
|
Term
|
Definition
| For measuring temperature. At sealevel water freezes at 0 and boils at 100, avg human body temp is 37 and room temp is 20-25 |

Definition
| The amount of energy it takes to raise the temperature of 1 gram of water 1 degree celsius, also the amount of energy released when 1 gram of water cools 1 degree celsius |
|
|
Term
|
Definition
| (Kcal), 1000 calories, or the amount of energy required to raise 1 kilogram of water 1 degree cesius |
|
|
Term
|
Definition
| Another measure of energy. It is equal to .239 cal, and one calorie equals 4.3 Joules |
|
|
Term
|
Definition
| The amount of heat that must be absorbed or lost for 1g of that substance to change its temperature by 1 degree celsius. For water it is 1 calorie per gram per degree celsius. Water will change its temperature less when it absorbs or loses a given amount of heat |
|
|
Term
|
Definition
| Quantity of heat a liquid must absorb for 1g of it to be converted from the liquid to the gaseous state. Waters is also high. Caused by H bonds Helps moderate Earth's temperature |
|
|
Term
|
Definition
| As a liquid evaporates, the surface of the liquid that remains cools down. This is because the "hottest" molecules are the ones to leave and go into gas. EX: himan sweat |
|
|
Term
|
Definition
| Because of the H bonds keeping the molecules of water at a greater distance which creates a less dense form |
|
|
Term
|
Definition
| A liquid that is a completely homogeneous mixture of 2 or more substances |
|
|
Term
|
Definition
| The dissolving agent of a solution |

Term
|
Definition
| One in which water is the solvent |
|
|
Term
|
Definition
| The sphere of water molecules around each dissolved ion. As when water dissolves NaCl crystals |
|
|
Term
|

Term
|
Definition
| The number of moles of solute per liter of solution. Unit of concentration used by biologists |
|
|
Term
|
Definition
| When the H bond in water is broken it forms one H+ ion and one OH- ion, then the free H+ ion joins with a water molecule to form Hydronium or H3O+ |
|
|
Term
|
Definition
| A solution with a higher H+ ion concentration. Created when acids donate additional H+ ion to a solution. They have pH of <7 on the pH scale |
|
|
Term
|
Definition
| A substance that decreases the H+ concentration, some directly accept the free H+ ions and some lose OH- ion which bond to the free H+. They have pH >7 on the pH scale |
|
|
Term
|
Definition
| The negative Logarithm (base 10) of the H+ concentration |
|
|
Term
|
Definition
| ubstances that minimize changes in the concentration of H+ and OH- in a solution. Ex: Buffers act to keep human blood at about pH 7.4 |
