- 1Bio 210 Campbell. Chapter 3 Water and life.
- 2AdhesionThe clinging of one substance to another, such as water to plant cell walls by means of hydrogen bonds.
- 3CohesionThe linking together of like molecules, often by hydrogen bonds
- 4Surface tensionA tension a measure of how difficult it is to stretch or break the surface of a liquid, water has a high surface tension because of the hydrogen bonding of surface molecules.
- 5Kinetic energyThe energy associated with the relative motion of objects. moving matter can perform work by imparting motion to other name.
- 6TemperatureA measure in degrees of the average kinetic energy (thermal energy) of the atoms and molecules in a body of matter.
- 7HeatThermal energy in transfer from one body of matte to another.
- 8Specific HeatThe amount of heat that must be absorbed or lost for 1g of a substance to change its temperature by 1 degree celsius.
- 9EvaporationThe conversion of a liquid into vapour, at temperatures below the boiling point.
- 10Evaporative coolingThe process in which the surface of an object becomes cooler during evaporation, a result of the molecules with the greatest kinetic energy changing from the liquid to the gaseous date.
- 11SolutionA liquid that is a homogeneous mixture of two or more substances.
- 12SolventThe dissolving agent of a solution. water is the most versatile solvent known.
- 13SoluteA substance that is dissolved in a solution.
- 14Aqueous SolutionA solution in which water is the solvent.
- 15HydrophilicHaving an affinity for water.
- 16HydrophobicHaving no affinity for water; tending to coalesce and form droplets in water.
- 17PH FormulaA measure of hydrogen ion concentration equal to -log[H+] and ranging in value form 0 to 14
- 18AcidA substance that increases the hydrogen ion concentration of a solution.
- 19BaseA substance that reduces the hydrogen ion concentration of a solution.
