Increasing temperature will have what affect on volume if pressure is held constant?
INCREASE of volume
At the boiling point of a liquid, what two pressures are equal?
VAPOR pressure = ATMOSPHERIC pressure
definition: number of collisions of the molecules with their container
(name the term)
PRESSURE
Which law applies to the following:
Volume varies directly with temperature (constant pressure)
Charles' Law
A sample of neon gas occupies a volume of 742 mL at 35˚C. What volume will the gas occupy at 60˚C if the pressure is held constant?
802 mL
As pressure increases what happens to volume if temperature is held constant?
DECREASE of Volume

definition: The amount of space that a gas occupies.
(name the term)
VOLUME
Which law applies to the following:
pressure varies directly with temperature (constant volume)
Gay-Lussac's Law
A 8.3 L gas sample at standard pressure is compressed to a volume of 2.8 L and the temperature is increased from 30˚C to 65˚C. What is the new pressure of the gas in atms?
3.3 atm
List the type of bonds in order of increasing molecular attraction
nonpolar, polar, ionic
I inflated a balloon to 1.1L at Diamond Lake today. The weather channel said that the temperature was -4˚C. and the pressure was 0.99atm. I took the day off and went scuba diving in Miami (obviously WITH the balloon). I dove 50ft, where the pressure was 2.52atm and the temperature was 15˚C. What size is the balloon now?
0.46L
Name the term defined by:

When 0.5L of steam is collected over boiling water (100˚C) at 0.87 atm, how many moles of water were collected?
0.0142 moles
The process of ______ from a surface ADDS heat energy.
The process of ______ from a surface REMOVES heat energy.
CONDENSATION
EVAPORATION
I inflated a balloon to 1.1L at Diamond Lake today. The weather channel said that the temperature was -4˚C. and the pressure was 0.99atm. I took the day off and hopped on a plane (obviously WITH the balloon) to Timbuktu, Mali. The Boeing 737 lost a window in flight and the balloon went flying out at 40,000ft, where the pressure was 0.184atm and the temperature was -56˚C. What size is the balloon now?
4.77L
R stands for what
(name it)
the Ideal Gas Constant
Which law applies to the following:
A relationship between volume, pressure, temperature, and number of moles of a gas
the Ideal Gas Law

621K
348˚C
Compared to sea level (STP), will water boil at a higher or lower temperature in Klamath Falls?
LOWER temperature
