Q1

The Ideal Gas Law is as follows:

is pressure as measured in Pascals, is volume as measured in cubic meters, is the number of moles of the gas, is the gas constant known as 8.314 Joules per mole times Kelvin, and is the temperature measured in Kelvin.

A class of students began studying the Ideal Gas Law and how the Pressure and the Volume relate to one another. They took 20 moles of a sample gas and kept the room at a temperature of 300 Kelvin. They then used different sized containers of the gas to limit and expand the volume. At each different volume, they measure the pressure of the gas on its container. The table they made from their results is seen in table 1.

Temperature in KelvinPressure Measured in Pascals
200 Kelvin16, 628 Pascals
400 Kelvin33, 256 Pascals
600 Kelvin49, 884 Pascals
800 Kelvin66, 512 Pascals

FIGURE 1

The graph the students made based on the data is seen in Figure 1.

Pressure is created by the movement of the gas molecules pushing against a container. 0 Kelvin is known as absolute 0, the temperature at which all molecule movement theoretically stops.

If the equation that converts temperature Kelvin to temperature in degrees Fahrenheit is

what is the pressure of the sample gas at the freezing point of water, which is 32 degrees Fahrenheit?
