The only factor that determines the boiling point of water at any altitude is the barometric pressure (the altitude itself doesn't actually matter, it's just that at higher elevation, the barometric pressure usually drops). However, water will boil at two different temperatures at the same elevation if you are in a high pressure weather system instead of a low pressure system. See the two Web Links listed to the left of this to find a chart of the standard barometric pressure at different altitudes (SableSys.com). Also, I've linked a very easy to use calculator to find the boiling point of water at any given barometric pressure (PrimoGrill.com). Just enter the pressure (the absolute pressure, not relative) and it gives you the boiling point! As an example, here are the numbers under standard conditions for 7000 ft: At 7000 ft, the standard barometric pressure is 23.088 inches Hg, and so water boils at 199.3 degrees Fahrenheit or 199.3 °F, which is equal to 92.94 degrees Celsius, or ... more

Liquid volume is measured with beakers, measuring cups, spoons, graduated cylinders, and the like. For regular objects, solid volume can be calculated. For irregular objects, their volumes can be determined by measuring the amount of liquid that is displaced by the object when it is submerged in the liquid. It is also used to measure the amount of pigs that fall from the sky!!! What is a Newton meter? A unit of energy also known as a Joule. When a force of 1 Newton is applied on an object for a distance of 1 meter then 1 Joule of energy is used. It is the result of a ... more
