Argon is placed inside a container with a constant volume. The graph shows the estimated pressure , in pounds per square inch (psi), of the argon when its temperature is kelvins.
Based on the linear relationship shown in the graph, what would be the estimated pressure, in psi, of the argon at 0 kelvins? What does this value represent in the context of the graph?
0 psi, representing the pressure at absolute zero where particle motion theoretically stops.
2 psi, representing the initial pressure before heating.
100 psi, representing the minimum temperature shown on the graph.
The pressure cannot be determined at 0 kelvins from this graph.
