Three sealed containers, X, Y and Z, each contain the same mass of the same gas.
The Table shows the volume of each container and the temperature of the gas in it.
Table
| Container | Volume in litres | Temperature of gas |
|---|---|---|
| X | 2.0 | 300 K |
| Y | 1.0 | 27 ∘C27\ ^{\circ}\text{C}27 ∘C |
| Z | 2.0 | 87 ∘C87\ ^{\circ}\text{C}87 ∘C |
Explain which of containers X and Y has the higher gas pressure.
Explain whether the gas pressure in container Z is higher or lower than the gas pressure in container X.
The gas pressure in container X is 150 kPa.
Calculate the gas pressure in container Y.
Use the equation
P1×V1=P2×V2P_1 \times V_1 = P_2 \times V_2P1×V1=P2×V2
