A 10-pound propane tank can hold approximately 2.4 gallons of propane.
Assuming the propane cylinder you mentioned is a standard 20 lb propane tank, it would hold around 4.7 gallons of water. This varies depending on the specific dimensions of the tank.
Because the propane in the tank is mostly liquid and as the propane gas at the top of the tank is removed to be burned the liquid propane must evaporate to replace it. Evaporating a liquid requires heat, which the liquid takes from things around it. The tank is in closest contact with the liquid propane, so it cools fastest.
A 15-pound propane tank holds less propane than a 20-pound tank, with the numbers indicating the weight of the propane the tank can contain. Specifically, a 15-pound tank can hold about 3.6 gallons of propane, while a 20-pound tank holds approximately 4.7 gallons. This difference affects the tank's usage time and how long a grill or heater can run before needing a refill. Additionally, the physical size and weight of the tanks differ, making the 20-pound tank heavier and larger.
