 Polar Molecule opposite ends of teh molecule have opposite charges cohesion binding of "like" molecules adhesion binding of different molecules surface tension a measure of how difficult it is to stretch or break the surgace of a liquid Kinetic Energy energy of motion Heat measure of the total quantity of kinetic energy due to the molecular motion in a body of matter Temperature measures the intensity of heat due to the average kinetic energy of the molecules Celsius Scale used to indicate temperature Calorie the amount of heat energy it takes to raise the temperature of 1g of water by 1 degree Celsius Kilocalorie the amount of heat energy it takes to raise the temperature of 1kg of water by 1 degree Celsius Joule energy unit. 4.184 of these equals a calorie Specific heat a substance is defined as the amount of heat that must be absorbed or lost for 1g of that substance to change its temperature by 1 degree celsius. Heat of Vaporization the quantity of heat a liquid must absorb for 1g of it to be converted from the liquid to the gaseous state evaporative cooling as liquid evaporates, the surgace of the liquied that remains behind cools down Solution a liquid that is a homogeneous mixture of two or more substances Solvent dissolving agent Solute substance being dissolved Aqueous Solution solution in which water is the solvent Hydration shell a sphere of water molecules around each dissolved ion hydrophilic water loving; ionic or polar hydrophobic water hating; non-ionic or nonpolar Mole equal in number to the molecular weight of a substance Molecular Weight the sum of the weights of all the atoms in a molecule Molarity the number of moles of solute per liter of solution Hydrogen ion a single proton with a charge of +1 Hydroxide ion water molecule that lost a proton Acid a substance that increases the hydrogen ion concentration of a solution base a substance that reduces the hydrogen ion concentration of a solution is called a base Acid precipitiation rain, snow, or fog with a more acidic ph than 5.6
