Question

How are the graphs for:?

>Boyle's Law
>Pressure Law
_>Charles Law

Answer 1

Boyle's Law : At constant temperature(`T`), pressure (`P`) of fixed amount of an ideal gas is inversely proportional to its volume(`V`)

`P prop 1/V`

or, `P=k/V` (where, `k` is a constant)

or, `PV = k`

this is an equation of rectangular hyperbola

And, `P` vs. `1/V` is an equation of straight line

Charle's Law: At constant pressure (`P`), the volume(`V`) of fixed amount of an ideal gas is directly proportional to its temperature (`T`) in Kelvin scale.

`V prop T`

or, `V=cT` (where, `C` is a constant)

this an equation of straight line passing through origin.

Gay-Lussac's Law or Pressure Law: At constant volume(`V`) the pressure(`P`) of fixed amount of an ideal gas is directly proportional to its temperature(`T`) in Kelvin scale.

`P prop T`

or, `P = bT` (where, `b` is a constant)

so,this is also an equation of straight line passing through origin.
