the gas cylinder we use at home has LPG in the form of a liquid however when we switch on of a stove it first converts to gas which burns what form of change is this. explain with reason
Answers
Answer:
it could be that there is converter
Answer:
Explanation:
LPG is a fuel which is very easy to transport because it is liquifiable at moderate pressures. LPG liquid expands 250 times when it converts to vapor.
When the LPG is used in a stove, the LPG liquid boils to create vapor. This process requires heat (latent heat of vaporization) which is absorbed from the LPG liquid and the container their by reducing the temperature of the cylinder.
When the LPG is used up at moderate speed (2–3 burners), the heat required is minimal and the reduction in temperature of cylinder is not felt. When the usage is higher, the cylinder starts sweating.
To answer your question, only one change takes place which is change of phase from liquid to vapour.
