Term | Definition |
Four Emergent Properties of Water- | cohesion/adhesion, moderation of temperature, evaporative cooling, excellent solvent |
Cohesion/Adhesion- | water molecules stick together, which “holds water together” and gives water surface tension |
Moderation of Temperature- | water resists change in temperature |
Specific heat- | the amount of heat energy (gained or lost) required to change 1 g of a substance by 1 degree Celsius |
Q. Why does water have a high specific heat- | A. it is a polar molecule and it forms hydrogen bonds |
Evaporative Cooling- | reduction in the temperature of water resulting from evaporation of liquid |
Solvent- | many substances have an affinity for water, they can partially or fully dissolve in it |
Water dissociates- | water falls apart at low rates |
Acid- | substances that increase the proton concentration |
Base- | substances that decrease the proton concentration |
Hydrophobic- | repels water |
Hydrophilic- | has an affinity for water |
7 on pH scale- | neutral |
Less than 7 on pH scale- | acid |
Greater than 7 on pH scale- | base |
Buffers- | minimize change in pH, proton concentration, and electron concentration |
