Question

what are the two forms of LPG we observe in our daily life . What type of change occurs when these two states interchange ?​

Answer 1

Answer:

LPG is mixture of flammable hydrocarbon gases that include propane, butane, isobutane and mixtures of the three LPG gases. LPG is commonly used for home heating gases, cooking, hot water, and autogas – fuel for LPG cars and vehicles.

It is stored pressurised, as a liquid, in cylinders or tanks

SO ,here the gas is compressed to form liquid .  

In our daily life we see two forms of  LPG

first form is LIQUID (in cylinder)

and the other as  GAS  ( when that liquid gas is heated ).

 So ,here

first gas is compressed to form liquid

and liquid is  heated to form gas.
