Question 10
HA student investigates how the pressure of a fixed mass of gas depends on its volume at constant temperature. Figure 1 shows a graph of the student's results.
Figure: a graph of the pressure of a fixed mass of gas against its volume at constant temperature
a.[1]
Use Figure 1 to determine the pressure of the gas when the volume of the gas is 25 cm3.
b.[3]
Determine the value of pressure×volume\text{pressure} \times \text{volume}pressure×volume for the gas in Figure 1. Give the unit.
c.[2]
Explain why the graph is a curve and not a straight line.
