the attractive force that causes identical molecules, especially water molecules, to stick together (surface tension).

the binding or attraction between dissimilar cells, molecules, or surfaces.

the movement of water into, through and out of organisms

How do plants transport so much water?

Evaporation, cohesion, and adhesion work together

Thermal(heat) energy:

kinetic energy associated with random motion of atoms or molecules

amount of heat that must be absorbed to change temperature by 1 °C

heat required to raise temperature of 1g of water by 1°C

Fastest water molecules leave slowing down the remaining molecules

Contain carbon. Organisms are largely carbon-based

capable of forming 4 covalent bonds at the same time.

Carbon has a complex...

a simplified drawing of an organic molecule that shows carbon-carbon bonds as atoms.

a way to write a chemical molecule's structure in a single line of text without drawing every individual bond.

a simplified shorthand drawing of a n organic molecule where lines represent carbon-carbon bonds and carbon atoms are placed at line ends and bends.

a drawing style that combines two different types of chemical representations.

one of two or more compounds that have the same molecular formula but differ in the covalent arrangements of their atoms.

Cis-trans isomers(geometric isomers):

one of several compounds that have the same molecular formula and covalent bonds between atoms but differ in the spatial arrangements of their atoms owing to the inflexibility of double bonds.

isomers that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon.

contain only hydrogen and carbon. May come from degradation of organic molecules. They are nonpolar because carbon an hydrogen share electrons almost equally.

each has certain properties, such as shape and charge, that cause it to participate in chemical reactions in a characteristic way.

Term	Definition
Cohesion:	the attractive force that causes identical molecules, especially water molecules, to stick together (surface tension).
Adhesion:	the binding or attraction between dissimilar cells, molecules, or surfaces.
Water transport:	the movement of water into, through and out of organisms
How do plants transport so much water?	Evaporation, cohesion, and adhesion work together
Kinetic energy:	energy of motion
Thermal(heat) energy:	kinetic energy associated with random motion of atoms or molecules
Specific heat:	amount of heat that must be absorbed to change temperature by 1 °C
Calorie (cal):	heat required to raise temperature of 1g of water by 1°C
Heat is absorbed when:	Hydrogen bonds break and form
Evaporative cooling:	Fastest water molecules leave slowing down the remaining molecules
Organic Compounds:	Contain carbon. Organisms are largely carbon-based
Carbon is...	capable of forming 4 covalent bonds at the same time.
Carbon has a complex...	structure that allows double bonds to take place
carbon skeletal notation:	ways to note how compounds are formed
Bond-line formula:	a simplified drawing of an organic molecule that shows carbon-carbon bonds as atoms.
Condensed Formula:	a way to write a chemical molecule's structure in a single line of text without drawing every individual bond.
Line formula:	a simplified shorthand drawing of a n organic molecule where lines represent carbon-carbon bonds and carbon atoms are placed at line ends and bends.
Hybrid notation:	a drawing style that combines two different types of chemical representations.
Isomers:	same formula, different shape
Structural Isomers:	one of two or more compounds that have the same molecular formula but differ in the covalent arrangements of their atoms.
Cis-trans isomers(geometric isomers):	one of several compounds that have the same molecular formula and covalent bonds between atoms but differ in the spatial arrangements of their atoms owing to the inflexibility of double bonds.
Enantiomers:	isomers that are mirror images of each other and that differ in shape due to the presence of an asymmetric carbon.
Hydrocarbons:	contain only hydrogen and carbon. May come from degradation of organic molecules. They are nonpolar because carbon an hydrogen share electrons almost equally.
Functional Groups	each has certain properties, such as shape and charge, that cause it to participate in chemical reactions in a characteristic way.
