SCIENCE QUESTIONS!? a gas barbecue grill uses propane gas, the propane is stored in a rigid tank, what happens?
what happens to the pressure of the propane when the tank is left outside on a very hot summer day? what about on a cold winter day?
The pressure in a propane vessel is directly related to the temperature.
At -44 degrees fahrenheit, or celsius, a propane container will have zero pressure. As the temperature of the liquid propane in the container increases, the pressure will increase. The size of the container is not a factor. At a given temperature, the pressure is the same in a 20lb BBQ cylinder as it is in a 3600 gallon truck as it is in a 30,000 gallon storage tank…
About the most pressure you will have in a home heating tank or a barbecue is around 200 psi.
Propane appliances operate on 11" w.c. which is roughly 1/2 psi, so it doesn’t take a lot of temperature for a grill to operate perfectly fine on a 20lb cylinder…
Pressure increases with temperature.
