When gas from a cooking gas cylinder is used, the pressure does not fall appreciably until the last few minutes. Why?
This was a question in one of my reference books and I couldn't answer it. Didn't find anything useful on google too. I am not able to figure out why the pressure in the cylinder doesn't drop below atmospheric pressure and how is it able to supply the gas, till it is almost over. Can anybody help me find the reason for this phenomenon?
Thank you :)
