How long does butane fuel last?

Answer 1

That depends on the ambient conditions.

The rate at which butane evaporates depends on the ambient pressure, the temperature and the amount of ambient convection. If the butane is very cold, it will take an extremely long time to evaporate. If it is hot, it will pretty much flash into vapor as soon as it is exposed to atmospheric pressure. If it is in the bottom of a long tube where the vapor above the liquid quickly becomes entirely composed of butane, it will evaporate more slowly than if it is just dumped out in a puddle on the ground with a fan blowing over it. Since the vapor pressure of butane is around 2 atmospheres at typical room conditions, it will generally be under pressure in whatever container it is stored in. As soon as the container is opened, it will start boiling. Butane lighters have liquid butane in them because the plastic doesn't have too much trouble containing the relatively low pressure required to keep most of the butane liquid. If you drill a hole in the side of one, the butane will start boiling until all but a bit of residual vapor has escaped.

Answer 2

The duration of butane fuel can vary depending on usage, but a standard small canister may last for a few hours of continuous use on a portable stove. It's recommended to keep track of usage and have backup canisters available for longer trips or extended cooking needs.

Answer 3

if u can imagine it, i lighter would fill a room about 6m by 9m with flame

Answer 4

Butane evaporates faster than water because its vapore pressure is lower than water and the molecules are more active and go faster
