In the ideal gas law, this variable represents the amount of gas present.
What is n?
The standard unit for volume when using the ideal gas law.
What are liters?
STP stands for this.
What is standard temperature and pressure?
Weather balloons expand as they rise because external pressure does this.
What is decrease?
If temperature doubles (in Kelvin), pressure will do this.
What is double?
Rearranging PV = nRT to solve for temperature gives this expression.
What is PV/nR?
The standard unit for pressure when using the ideal gas law.
What are atmospheres?
The standard temperature, in oC.
What is 0oC?
This device measures atmospheric pressure.
What is a baromteter?
If pressure is cut in half, volume will do this (assuming constant temperature).
What is double?
Gay-Lussac's law shows the relationship between temperature and this variable.
What is pressure?
The units for the gas constant R, when R has a value of 0.0821.
What is atm.L / mol.K?
At STP, one mole of gas occupies this volume.
What is 22.4 L?
When a SCUBA diver rises to the surface, this happens to the volume of the gases in their lungs.
What is it increases?
The changing conditions equation solved for V1 when number of moles is kept constant.
What is T1P2V2 / P1T2?
This law describes the relationship between pressure and volume at constant temperature.
What is Boyle's Law?
The value of R to the nearest tenth when pressure is in kPa, volume is in L, and temperature is in K.
What is 8.3?
The number of moles for 67.2 L of a gas at STP.
What are three moles?
This term describes the ratio of coefficients in a balanced equation.
What is stoichiometry?
The temperature, to the nearest oC, at which 50.0 grams of O2 occupy 20.0 L at a pressure of 105 kPa.
What is -111oC?
This law relates volume and temperature when pressure is constant.
What is Charles's Law?
This old unit for pressure, beginning with the letter 't,' means the same thing as mmHg.
What is torr?
The gas that is at STP from the following:
Gas A: 11.2 L container with 16 g of oxygen gas
Gas B: 22.4 L container with 14 g of nitrogen gas
Gas C: 44.8 L container with 16 g of helium gas
What is Gas A?
This medical device relies on pressure-volume relationships to function.
What is a syringe?
The volume of CH4, to the nearest liter, needed at 30.5oC and 1.04 atm to produce 10.0 grams of H2O.
CH4(g) + 2 O2(g) --> CO2(g) + 2 H2O(l)
What is seven?
