100
average kinetic energy of the molecules is directly propotional to this
what is temperature
100
pressure varies inversely with volume (temp is constant)
What is Boyle's Law
100
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?
What is 237 mL
100
an imaginary gas that conforms perfectly to all the assumptions of the kinetic theory
What is an Ideal Gas
100
the sum of the individual pressures of the gases mixed together in the atmosphere.
Who is atmospheric pressure
200
number of collisions of the molecules with their container
What is pressure
200
Volume varies directly with temperature (constant pressure)
What is Charles' Law
200
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?

200
Atmospheric pressure is measured using this instrument
Who is a Barometer.
300
273 Kelvin or 0˚C and 1 atmosphere, 760 mmHg/torr, or 101.3 kPa.
What is STP (standard temperature and pressure)
300
pressure varies directly with temperature (constant volume)
What is Gay-Lussac's Law
300
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?
What is 3.3 atm
300
Gases consist of larger number of tiny particles, particles of a gas are in constant motion, the collisions between particles and their container are elastic, theare are no attractive or repulsive forces between gas particles, and the average kinetic energy of the particles of a gas is directly proportional to the Kelvin temperature of the gas.
What is the Kinetic Theory of Matter.
300
Used to measure the pressure of a specific gas in comparison to atmospheric pressure
What is a Manometer
400
The amount of space that a gas occupies.
What is volume
400
combination of other three gas laws
What is the Combine Gas Law
400
When hydrogen gas is collected over water at 30˚C, (water vapor pressure 31.8 mmHg) the partial pressure of the hydrogen gas was determined to be 732.8 mmHg. What was the barometric pressure at the time the gas was collected?
What is 765 mmHg
400
Real vs. Ideal: 1.) Particles of a gas occupy space and have mass. 2.) Particles of a gas exert attractive forces on one another.
What is a Real Gas.
400
As pressure increase what happens to volume if temperature is held constant
What is decreases
500
The R stands for what in the Ideal Gas Law.
What is the Ideal Gas Constant
500
A relationship between volume, pressure, temperature, and number of moles of a gas
