Some gas is put into a syringe. The initial volume of the gas in the syringe was 12 cm3.The initial pressure of the gas in the syringe was 101 000 Pa. Calculate the constant
12,120,000 Pa cm3
0.00011 Pa cm3
8416 Pa cm3
1,212,000 Pa cm3
When the volume of gas in a syringe was 45 cm3, the pressure gauge showed a value of 60 kPa. Calculate the pressure in the gas when the volume of gas in the syringe was 40 cm3.

70.0 kPa
60 kPa
The pressure of helium in a balloon is 100 000 Pa. The volume of the balloon is 0.030 m3. The balloon is compressed at a constant temperature causing the volume to decrease to 0.025 m3. No helium leaves the balloon. Calculate the new pressure in the balloon.
140 000 Pa
80 000 Pa
100 000Pa
120 000 Pa
pressure = 1.6 × 105 Pa
Volume = 9.0 cm3
Calculate the volume of the gas when the pressure was 1.8 × 105 Pa. The temperature of the gas was constant.
10.0 cm3
8.0 cm3

How confident are you are using pV = constant?
This was easy, I got most of them right
I got some right but I will need to try some more when I revise
I didn't really understand how to re-arrange the equation but I could substitute. I didn't get many right.
I don't understand how to substitute the terms so could not even attempt the maths
