|
STP |
1 atm. 0 C. |
|
|
a mixture of compounds in the gas phase will be homogenous regardless of polarity. so far apart they do not exert significant significant forces on one another. |
wow so cool |
|
|
internal and external pressure of a flexible container are always the same |
yep. it adjusts to match. balloon in decreasing temp will shrink. V decreases, not P. |
|
|
1 atm in torr/mmhg |
760 |
|
|
adiabatic process |
no heat is transferred |
|
|
standard molar volume |
at 1 atm and 0 degrees C, 1 mol gas will occupy 22.4 liters |
|
|
ideal vs real volume of gases |
real gases have molecules with volume, so real volume increases |
|
|
ideal vs real pressure of gases |
real gases have imf's which are mostly attractive. so this decreases their pressure. real pressure decreases. |
|
|
heat capacity is greater at constant pressure because it can expand, doing pv work. |
this is why pressure cookers are at constant volume. so no heat is lost, they boil faster. Cp is more than Cv |
|
|
heat of vaporization is usually larger than heat of fusion |
but gas C is usually lower than solid or liquid C. |
