Quiz Answer Key and Fun Facts

Answer:
**Ideal Gas Law**

The ideal gas law has 5 variables. Given 4 of the variables, it is possible to determine a fifth variable.

Pressure x Volume = Moles x Gas Constant x Temperature

The ideal gas law has 5 variables. Given 4 of the variables, it is possible to determine a fifth variable.

Pressure x Volume = Moles x Gas Constant x Temperature

Answer:
**0.0821**

The variable "R" in the ideal gas law always will be the same if the pressure is measured in ATM and the temperature is measured in Kelvin. "R" is known as the gas constant.

The variable "R" in the ideal gas law always will be the same if the pressure is measured in ATM and the temperature is measured in Kelvin. "R" is known as the gas constant.

Answer:
**Pressure and volume**

Boyle's law relates the pressure and the volume of a gas as long as the temperature remains constant.

Boyle's law relates the pressure and the volume of a gas as long as the temperature remains constant.

Answer:
**Law of volumes**

Charles's Law is named for Jacques Charles who carried out experiments in the latter part of the eighteenth century. He described how gases expanded when heated and contract when they cool.

Answer:
**P-1 + P-2 + P-3 = P-total**

John Dalton created this law showing that the sum of all the gas pressures is equivalent to the total pressure.

John Dalton created this law showing that the sum of all the gas pressures is equivalent to the total pressure.

Answer:
**Pressure & Temperature**

Gay-Lussac's Law relates the Pressure and the Temperature of a gas as long as the Volume remains constant.

Gay-Lussac's Law relates the Pressure and the Temperature of a gas as long as the Volume remains constant.

Answer:
**20 ATM**

Using the equation:

Pressure-1 x Temperature-2 = Pressure-2 x Temperature-1

You can then solve for the missing pressure.

(10 x 10 = P2 x 5)

Using the equation:

Pressure-1 x Temperature-2 = Pressure-2 x Temperature-1

You can then solve for the missing pressure.

(10 x 10 = P2 x 5)

Answer:
**1**

Many might think the answer is actually 2 but Hydrogen gas is diatomic. 2.02g x (1 mole / 2.02g) = 1 mole.

2.02g x (1 mole / 2.02g) = 2 moles

Other diatomic gases are Nitrogen, Oxygen, Fluorine, Chlorine.

Answer:
**-200 degrees Celsius**

The units are irrelevant with the freezing of the solution.

To change Celsius to Kelvin use the simple formula of:

(Degrees Celsius + 273 = Degrees Kelvin)

27 degrees Celsius = 300 degrees Kelvin, thus a -200 decrease in temperature.

100 degrees Kelvin = -173 degrees Celsius, thus a -200 decrease in temperature.

Answer:
**Number of Moles**

The only logical answer is the number of moles. The Pressure, Temperature, and Volume are all variable in the equation thus they can be changed. The equation shown is much simpler than memorizing individual rules like Charles's Law and Boyle's Law.
