The simple way to state Boyle's law :
Mathematically, V is proportional to (use the symbol) 1 all over p.
Terms:
V = volume at pressure p

Note : Boyle's law relationship can be expressed mathematically as p1 v1 = p2 V2 (where v1 = volume at pressure p1,V2 = volume at pressure p2).Boyle's law can be restated in the following way :
The pressure of a given mass of gas is inversely proportional to its volume, provided the temperature remains constant.
