Section 3.1 & Section 3.2 Flashcards
What is the clinging of one substance to another, such as water to plant cell walls by means of hydrogen bonds?
adhesion
What types of solutions have water as the solvent?
aqueous solution
What links like molecules together, often by hydrogen bonds?
cohesion
The amount of heat energy required to raise the temperature of 1 g of water by 1 degree Celsius.
calorie
The process in which the surface tension of an object becomes cooler during evaporation, a result of the molecules with the greatest kinetic energy changing from the liquid to the gaseous state.
evaporative cooling
Thermal energy in transferred from one body of matter to another.
heat
What is the quantity of heat a liquid must absorb for 1 g of it to be converted from the liquid to the gaseous state?
heat of vaporization
The sphere of water molecules around a dissolved ion.
hydration shell
A molecule that is has an affinity to water.
hydrophillic
A molecule that is has a fear, or no affinity to water.
hydrophobic
A thousand calories; the amount of heat energy required to raise the temperature of 1 kg of water by 1 degree Celsius.
kilocalorie
is the type of energy associated with the relative motion of objects.
kinetic energy
is the sum of all the masses of all the atoms in a molecule.
molecular mass
is the type of covalent bond between atoms that differ in electronegativity.
polar covalent bond
A is a molecule with an uneven distribution of charges in different regions of the molecule.
polar molecule
