Gas pressure and temperature

Easy

Figure 1a shows a gas syringe filled with air.

The gas has an initial pressure of $P_1\,$ and volume $V_1$ .

Figure 1b shows the same syringe after the plunger has been pushed in.

The pressure is now $P_2\,$ and the volume is $V_2$ .

The temperature of the gas does not change.

Figure 1a and Figure 1b: Diagrams of a gas syringe before and after compression

Use data from Figure 1a and Figure 1b to calculate the pressure $P_2\,$ of the gas in Figure 1b. Use the equation:

P_2 = \\frac{P_1 \\times V_1}{V_2}
