stands for Liquefied Petroleum gas. It is a mixture of
butane (C4 H10) and propane (C3
H8). They are stored in pressurized cylindrical
vessels. This is because these gases liquefy under moderate
pressure and vaporize on releasing the pressure. This
property of LPG enable it to transport and store it in the
liquid state, in which they are nearly 250 times as dense as
they are when gases.

is an odorless gas so an odorant (ethanethiol) is added to
