Question

Give the mathematical form of the following (a) Boyle's law (b) Charle's law

Answer 1

(a) Boyle's Law

It state that “at a constant temperature, The volume of a given mass of a gas is inversely proportional to the applied pressure”.

Mathematical form

$\mathrm{V}\times \frac{1}{\mathrm{P}}$

and ${\mathrm{P}}_1{\mathrm{V}}_1={\mathrm{P}}_2{\mathrm{V}}_2$(at constant temperature)

(b) Charle's Law

It states that “ the volume of a given mass of gas is directly proportional to its absolutely temperature at constant pressure.”

Mathematical form

$\mathrm{V}\times \mathrm{T}$

${\mathrm{V}}_1{\mathrm{T}}_2={\mathrm{V}}_2{\mathrm{T}}_1$ (at constant pressure)
