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.
|
Volume of the container |
Pressure Measured in Pascals |
|
1 cubic meter |
49,884 Pascals |
|
2 cubic meters |
24,942 Pascals |
|
3 cubic meters |
16,628 Pascals |
|
4 cubic meters |
12,471 Pascals |
|
5 cubic meters |
9,976.8 Pascals |
|
6 cubic meters |
8,314 Pascals |
|
7 cubic meters |
7,126.2 Pascals |
TABLE 1
And they graph their findings in Figure 1.
FIGURE 1
| 1. | If the Kelvin temperature were to rise, what would happen to the pressure? |
Pressure increases but only until Kelvin reaches 500, and then it decreases
The temperature has no predictable effect on the pressure because there are too many other variables
Pressure increases
Pressure remains constant
Pressure decreases
