What has the highest vapor pressure butane ethanol or toluene?
butane
What is the pressure in a usual refill butane that available in the market?
Do you mean propane? If not then a butane what eg. lighter or tank.
When butane evaporates whats left?
Butane is a gas at atmospheric pressure and room temperature. In the fuel tanks of cigarette lighters, butane welding torches, and most other butane powered heating devices, butane has been compressed to the point that it remains liquid at room temperature. When the trigger of these devices is depressed, a valve opens, allowing butane to escape from the tank, and in doing so, it's pressure drops to atmospheric pressure, and the liquid butane escaping the tank rapidly boils and becomes a gas, which is ignited by an ignition source. Strictly speaking, if the tank contained pure butane, when all the butane has evaporated, all that would be left in the tank is butane gas at atmospheric pressure. If you sprayed liquid butane on your table, and it were completely pure, the liquid would evaporate, leaving nothing behind. In reality, butane fuel is not completely pure, and may contain small amounts of all sorts of contaminants, some of which can be left behind after the butane evaporates. Some of these contaminants like methane, ethane, and propane likely would evaporate away with the butane, but other contaminants, like trace amounts of other petroleum distillates will likely remain after the butane evaporates.
Does butane freeze?
Yes, butane freezes at -138 degC or -216F. It boils (condenses) at -0.5degC or 31F, at normal atmospheric pressure.
Is butane found as a solid liquid or gas?
Butane boils at -1C and melts at -140C. Therefore, at -4C it is a liquid.
What has the highest vapor pressure butane ethanol or toluene?
butane
Is butane a gas at room temperature?
Butane is a gas at rtp (room temperature and pressure)

Does Butane have a lower vapor pressure than methylpropane?
Yes

Why does the liquid in a butane lighter become gas after being released?
It's the pressure in the lighter that keeps the butane liquid. When released into the atmosphere, under room pressure and temperature, returns to it's state of gas.
How long does butane fuel last?
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.
Does isobutane burn hotter than butane - Can you damage a backpacking stove made for burning butane by burning isobutane in it?
If I remember correctly i-butane is slightly higher pressure at room temperature than n -butane 45 psi vs 30 psi at room temperature. They buran at the same temperature for the same air/fuel ratio. The higher pressure would result is more fuel flow for the same orfice size. Your stove should have a control valve so it should not matter. Nost lighters and other things that say butane are actuall isobutane because it produces higher pressure and the lighter will function better at cold temperatrues. Your stove likely used isobutane any way. Propane is much higher pressure so don't simply substute propane for butane usless the device is made for propane as well.
Why does a butane lighter work poorly in cold weather?
The boiling point of Butane is approximately -0.5 C at sea level (This boiling point will drop with an increase in altitude given the reduced pressure). This means that as the lighter nears freezing less gas will be vaporized inside of the lighter and will make it hard to light.
