Gas Vocab
average kinetic energy of the molecules is directly propotional to this
Temperature
pressure varies inversely with volume (temp is constant)
Boyle's Law
A sample of oxygen gas collected in the lab occupies a volume of 250 mL when its pressure is 720 mmHg. What volume will the gas occupy at a pressure of 760 mmHg if the temperature is held constant? CONVERT TO LITERS!!!
0.24 L
number of collisions of the molecules with their container
Pressure
combination of other three gas laws
Combined Gas 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? CONVERT TO LITERS & KELVINS!!!
0.802 L
273 Kelvin or 0˚C and 1 atmosphere, 760 mmHg/torr, or 101.3 kPa are considered the _______________ values.
STP (standard temperature and pressure)
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? CONVERT ˚C TO KELVINS!!!
3.3 atm
The amount of space that a gas occupies.
Volume
A relationship between volume, pressure, temperature, and number of moles of a gas
Ideal Gas Law
The initial volume of a gas at a pressure of 3.2 atm is 2.9 L. What will be the volume if the pressure is increased to 4.0 atm?
2.3 L
R is called the __________ _______ __________.
Ideal Gas Constant
Volume varies directly with temperature (constant pressure)
Charles' Law
