How does air pressure affect the boiling point of a liquid apex?

There is always part of the liquid passing to the gas phase, and that gas makes a pressure – that is called vapor pressure. A liquid increases its vapor pressure as temperature rises, and the boiling point is reached when the vapor pressure of the liquid is equal to the atmospheric pressure. At a higher atmospheric pressure, the liquid will need to rise its temperature to an even higher temperature in order to reach enough vapor pressure. On the contrary, at a lower atmospheric pressure the liquid will reach the boiling point at a lower temperature.

This resource is commonly used for cooking. The pressure cooker makes food cook faster, because it works at 130°C instead of 100°C (at an atmosphere pressure of 1 atm, water can’t be at 130°C… because it is already vapor and it gets out of the pot). On the contrary, in sugar factories, they use a low pressure so that they can make water evaporate without cooking the sugar.

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.
