Question | Answer |
Force = | mass X acceleration |
What is the Si unit of force | Newton |
Pressure | Force/area |
1 atm in Pascals | 101,325 Pa |
Boyle's Law | The pressure exerted by a gas is inversely proportional to the volume the gas occupies. |
Pressure X Volume = | Constant |
Charles law | At constant pressure, the volume of a gas is directly proportional to the temperature in K of the gas |
Avogadro's law | For aq gas at a constant temperature and pressure the volume is directly proportional to the number of moles of gas |
The ideal gas law | Is a combination of all three gas laws pv=nRT |
Dalton's law of partial pressure | For a mixture of gases in a container the total pressure is the sum of the pressure that each gas would exert if it were alone |
Temperature | a measure of the average kinetic energy of a gas |
Diffusion | relates to the mixing of the gases |
Effusion | relates to the passag of a gas through an oriface into an evacuated chamber. |
energy | The capacity to produce work or heat |
Kinetic Energy | The energy of motion= 1/2 mass X(velocity)^2 |
Potential Energy | Energy that can be converted into useful work |
Heat | Involves the transfer of energy between two objects |
System | that which we are foccusing on |
Surroundings | everything else in the univerese |
Exothermic | Energy (as heat) flows out of the system |
Endothermic | Energy (as heat ) flows into the system |
When a system expands | it is doing positive work on the surroundings and negative work on the system |
When the system contracts | the surroundings have work done on the system there is positive work done on the system |
w= | -P X delta V |
The first law or The law of conservation | energy can be converted from one form to another but it can be neither created nor destroyed |
Delta E = | Q (heat) + W (work) |
Wavelength | Is the distance between two consecutive points in a wave |
Frequency | The number of waves per second that pass a given point in space |
Speed of light | (c) is in meters per second |
Planck's constant | 6.626*10^-34 |
Heisenburgs Uncertainty Principle | There is a limit to just how precise we can know both the posistion and mommentum of a particle at any given time |
Hunds rule | The lowest energy configuration for an atom is the one having the maximum number of unpaired electrons for a set of degenerate orbitals |
