If nonsalt water is placed in a closed system (for example an automotive cooling system) then for every pound of pressure the system can handle (ex. radiator cap) the boiling point of water (normally being 212f) is raised by 3 degrees. Thus, if said system can handle only 1 pound pressure before the water boils the temperature of the water when it boils should be 215F. Or so I understand.
Butane has a lower boiling point than water. Butane boils at -1°C (30.2°F) while water boils at 100°C (212°F) at standard atmospheric pressure.
Out of methane, ethane, propane, and butane, butane has the highest boiling point.
Butane would have the highest boiling point among ethane, propane, and butane.
Pressure changes have little effect on the boiling point of water. The boiling point of water changes depending on the pressure, but the effect is minimal compared to other factors like adding solutes or using a catalyst.
Butane lighters can work poorly in cold weather because the cold temperature affects the vaporization of butane, making it harder to ignite the flame. Lower temperatures can also decrease the pressure inside the lighter, making it difficult to generate the necessary spark for ignition.
Methane is the alkane with a boiling point of 0°C. It is a gas at room temperature and pressure.
Butane has a lower boiling point than water. Butane boils at -1°C (30.2°F) while water boils at 100°C (212°F) at standard atmospheric pressure.
Lowering the pressure the boiling point is also lower.
Out of methane, ethane, propane, and butane, butane has the highest boiling point.

Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.

The boiling point depends on altitude (pressure). The effect on the melting point is not significant.
The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
