yes it is necessary to subtract the water pressure
Butane is a gas at room temperature and pressure.
At room temperature, butane has the highest vapor pressure among the three compounds, followed by ethanol and then toluene. This means that butane will evaporate the fastest.
The pressure in a typical refill butane canister available in the market is usually around 2 to 2.5 bar, which is equivalent to roughly 29 to 36 psi. This pressure is sufficient to allow the butane to be dispensed as a liquid from the canister when it is inverted.
Butane is found as a gas at room temperature and pressure, but can be stored in a liquid form under pressure. It is not found naturally as a solid.
The butane phase diagram shows how butane can exist as a solid, liquid, or gas depending on the temperature and pressure. It illustrates the boundaries between these states and the conditions where each state is stable.

Butane is a gas at rtp (room temperature and pressure)
Butane is a colorless gas at room temperature and pressure.
The pressure in a typical refill butane canister available in the market is usually around 2 to 2.5 bar, which is equivalent to roughly 29 to 36 psi. This pressure is sufficient to allow the butane to be dispensed as a liquid from the canister when it is inverted.
Butane is found as a gas at room temperature and pressure, but can be stored in a liquid form under pressure. It is not found naturally as a solid.
The density of butane is approximately 0.58 grams per cubic centimeter at 25°C (77°F) and atmospheric pressure.

Yes
When the liquid butane in a lighter is released, it is exposed to lower pressure and higher temperature in the surrounding environment. This causes the liquid to evaporate and turn into a gas. The gas form of butane is what is ignited to create a flame when using a lighter.
Butane is not typically recommended for gas airsoft guns, as it burns at a lower pressure than the propane or green gas that these guns are designed for. Using butane can potentially damage the gun and may not provide the necessary power for proper operation. Stick to using the gas recommended by the manufacturer to ensure the best performance and longevity of your airsoft gun.
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.
