Test: ACT Science
The Ideal Gas Law is as follows:
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.

200 Kelvin |
16, 628 Pascals |
|
400 Kelvin |
33, 256 Pascals |
|
600 Kelvin |
49, 884 Pascals |
|
800 Kelvin |
66, 512 Pascals |
TABLE 1
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.
| 1. | 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? |
