3. Water And The Fitness Of The Environment Flashcards
What is Cohesion?
Attractive between like molecules.
What are the four water properties that enable an environment for life?
Cohesive behavior
Temperature moderation
Expansion upon freezing
Versatility as a solvent
What function does cohesion play?
Cohesion helps in transport of water against gravity in plants.
What is Adhesion?
Adhesion is an attraction between different substances.
What is Surface Tension?
Surface Tension is a measure of how hard it is to break the surface of a liquid.
What is Kinetic energy?
Kinetic energy is energy in motion.
What is heat?
Heat is the total amount of kinetic energy due to molecular motion.
What is temperature?
Temperature is the measure of intensity of heat due to the average kinetic energy of molecules.
What is Specific heat?
Specific heat is the amount of heat lost or gained to change the temperature by 1°C
What is Heat of Vaporization?
Heat vap. Is the the heat a liquid must absorb for 1g to be converted to gas.
What is evaporative cooling?
Evap. cooling is a process where liquid evaporated and leaves the remaining surface cool.
What is a Solution?
A liquid that is a homogenous mixture of substances.
What is a solvent?
The dissolving agent of a solution.
What is a solute?
The substance that is dissolved.
What is an Aqueous solution?
A solution which water is the solvent.
