# Boyle's Law : what are the comparisons of the gas pressure,P and the volume of the gas,V values?

what are the comparisons can be made of PV values when an open tube is move up to the highest point as possible and the values when an open tube is move down to the lowest point as possible in Boyle's Law experimment?

thanx.

Boyle's Law states that: "At constant temperature, the volume of a given mass of gas is Inversely Proportional to its Absolute Pressure".

P1 x V1 = P2 x V2.

Pressure increase <===> Volume Increase (and vice versa) at constant temperature.

At a higher elevation, the atmospheric pressure will be decreased. The volume of gas will therefore Increase...and vice-versa for a low elevation.

Boyle's Law:

PV = k

Thus the largest volume has the lowest pressure and vice versa. Still must multiply to get the same constant k.

Look at this:

Boyle's Law states that P is inv. proportional to V

Therefore, PV = constant

That is under the same conditions, differing P and V values when multiplied will have the same value.

If P is high, V will be low

If P is low, V will be high under the same conditions.

That is the logic.
