Term
| what are the three areas of P chem |
|
Definition
| thermodynamics, quantum mechanics, & chemical kinetics |
|
|
Term
| when looking at a graph, which portion pertains to physical chemistry |
|
Definition
| the X-axis which can include units of wavelength, velocity and time |
|
|
Term
| when do gases behave ideally |
|
Definition
| when there are low concentrations of them |
|
|
Term
| what is the ideal gas law |
|
Definition
|
|
Term
| in p chem, the more widely used equation, derived from the ideal gas law, is what |
|
Definition
|
|
Term
| how can pressure be derived |
|
Definition
P=F/A
force per unit area |
|
|
Term
| besides writing pressure as: F/A, how else can you write it |
|
Definition
(1) F=mg
(2) m=V(p) (volume & density)
(3) F/A=(p)h(A)g/A
(4) P=p(h)g
Pressure equals density * height * gravity |

|
Term
| what are the units for ideal gas laws |
|
Definition
|
|
Term
| how does the complexity of a structure affect its affinity to follow the gas law |
|
Definition
| as molecules become more complex, they tend to deviate from the ideal gas law |
|
|
Term
| what did van der Waals do to receive the Nobel Prize |
|
Definition
| for his work on the equation of state for gases and liquids |
|

Term
| what does extensive variables mean to you |
|
Definition
| that they are directly proportional to the size of the system |
|
|
Term

|
Term
| what does intensive variables mean to you |
|
Definition
| they are not directly proportional to the size of the system |
|
|
Term
| give examples of intensive properties |
|
Definition
| pressure, temperature and density |
|
|
Term
when we divide an extensive property by the number of moles in the system we get an
take for instances V |
|
Definition
| intensive variable called V (bar) |
|
|
Term
| calculate the pressure exerted by a 76.00 cm column of mercury. take the density to be 13.596 |
|
Definition
| ~1.0133 x 10^(6) g*cm-1*s-2 |
|
|
Term
| how would you solve a problem that asks you to convert pressure to pascals |
|
Definition
x(10^-6) is our imaginary pressure
x(10^-3)(100)
x^5 |
|
|
Term
|
Definition
| defined as 1.01325 x 10^5 Pa |

Term
| what is the definition of T (temperature) |
|
Definition
| T equals the limit as P approaches zero P times V bar divided by R |
|
|
Term
| in the context of defining temperature, what is the lowest possible temperature |
|
Definition
| since P and V bar cannot take on negative values, the lowest possible value for temperature is 0K |
|
|
