Polar Molecule
that the two ends of the molecule have opposite charges TERM 2
Cohesion
DEFINITION 2 the bonding together of like molecules, likely by hydrogen bond TERM 3
Adhesion
DEFINITION 3 the clinging of one substance to another. Adhesion of water to cell walls by hydrogen bonding helps counter the downward pull of gravity TERM 4
Surface
Tension
DEFINITION 4 Surface tension is a property of the surface of a liquid that allows it to resist an external force. A measure of how difficult it is to stretch or break the surface of a liquid TERM 5
Kinetic Energy
DEFINITION 5 The kinetic energy of an object is the energy which it possesses due to its motion. Energy of motion
Heat
measure of the matter's total kinetic energy due to its motion of it molecules TERM 7
Temperature
DEFINITION 7 is a measure pf heat intensity that represents the average kinetic energy of the molecules, regardless of volume. TERM 8
Calorie
DEFINITION 8 amount of heat it takes to raise the temperature of 1g of water by 1 C TERM 9
Kilocalorie
DEFINITION 9 the quantity of heat required to raise the temperature of 1 kilogram of water by 1 degree C TERM 10
Joule
DEFINITION 10 one joule equals 0.239 cal named after James Prescott Joule
Solute
The thing being dissolved TERM 17
Aqueous Solution
DEFINITION 17 An aqueous solution is a solution in which the solvent is water. TERM 18
Hydration Shell
DEFINITION 18 the sphere of water molecules around each dissolved ion TERM 19
Hydrophilic
DEFINITION 19 A hydrophile, from the Greek (hydros) "water" and (philia) "love," is a molecule or other molecular entity that is attracted to, and tends to be dissolved by, water. TERM 20
Hydrophobic
DEFINITION 20 In chemistry, hydrophobicity (from the combining form of water in Attic Greek hydro- and for fear phobos) is the physical property of a molecule (known as a hydrophobe) that is repelled from a mass of water.
Colloid
A colloid is a substance microscopically dispersed evenly throughout another one. A stable suspension of fine particles in a liquid TERM 22
Molecular Mass
DEFINITION 22 the sum of all the masses in that molecule TERM 23
Mole
DEFINITION 23 Avagadro's Number. Represents 6.02 X 10^ TERM 24
Molarity
DEFINITION 24 the number of moles of solute per liter of solution TERM 25
Hydrogen Ion
DEFINITION 25 a single proton with a charge of +
