Physical Chemistry> intensive and extensive properties...

question mark

Why pressure is an intensive property?

as per boyle's law, pressure changes with volume. so the pressure of a gas depends upon the volume and not the nature of gas. so it should be extensive propoerty. why it is an intensive property?????

Dear Deeksha,

Your doubt is very genuine.Let me clear it here only.

Let us take a gas p= 1atm and V = 1 L.
We divide the gas into two equal parts.
Pressure is always 1 atm and volume is 0.5 L
If a quantity of matter is divided into two equal parts each part will have the same value of intensive property as the original and half the value of extensive property.

See it depends on the case;

For isothermal condition ,pressure will be an extensive property.

But as according to when volume changes but pressure remains same ,there the temperture tends to change .So this also results that temperature can be an extensive property too.
