results from the collisions of air molecules with objects
What is atmospheric pressure
100
the accurate and precise measurement of heat change for chemical and physical processes
What is Calorimetry
100
a measure of how much the volume of matter decreases under pressure
What is compressibility
100
in forming compounds, atoms tend to achieve the electron configuration of a noble gas.
What is octet rule
100
a solution that contains less solute than a saturated solution
What is unsaturated
200
a conversion occurs at the surface of a liquid that is not boiling
What is evaporation
200
the heat lost when one mole of a liquid solidifies at a constant temperature
What is molar heat of solidification
200
states that for a given mass of gas at constant temperature, the volume of gas varies inversely with pressure.
What is Boyle's law
200
the forces of attraction that bind oppositely charged ions
What is ionic bonds
200
if they dissolve in each other
What is miscible
300
the temperature at which a solid turns into a liquid
What is melting point
300
a compound is the change in enthalpy that accompanies the formation of one mole of a compound from its elements with all substances in their standard states at 25 degrees Celsius
What is standard heat of formation
300
states that the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant
What is Charles law
300
the number of ions of opposite charge that surround the ion in a crystal
What is coordination number
300
a solution that contains more solute than it should theoretically continue to hold at a given temperature
What is supersaturated
400
states that the tiny particles in all forms of matter are in constant motion
What is kinetic theory
400
if you add two or more thermochemical equations to give a final equation, then you can also add the heats of reaction to give the final heat of reaction.
What is Hess's law of heat summation
400
states that the pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant.
What is Gay- Lussac's law
400
consist of the attraction of the free-floating valence electrons for the positively charges metal ions.
What is metallic bonds
400
contains a high concentration of solute
What is concentrated solution
500
defined as the boiling point of a liquid at a pressure of 101.3 kPa
What is normal boiling point
500
the heat of reaction for the complete burning of one mole of a substance
What is heat of combustion
500
Equal volumes of gases at the same temperature and pressure contain equal numbers of particles.
What is Avogadro's hypothesis
500
ions that are produced when atoms of chlorine and other halogens gain electrons
What is halide ion
500
which depend only on the number of particles dissolved in a given mass of solvent
