True or false the boiling point of water can be 98 degrees Celsius at 1100 feet elevation and 100 degrees Celsius at sea level?

Answer 1

The boilding point of water wherever you are is about 100 degrees celsius. As long as the object is the temporature, isn't doesn't matter whats around it. the only affect it'll have is either reducing the temperature of the actuall object or increasing it. The state changes still stay the same, however.

The thing that affects the boiling point of water is barometric pressure. Generally speaking, the barometric pressure at higher altitudes is a bit lower than at sea level, but not enough through an 1100 foot altitude change to make a difference of 2 degrees Celsius. If you were at the high base camp on Everst, you'd see a bit of a difference, but generally you wouldn't.

Note that a large change of barometric pressure will effect a big change of boiling point. Vacuum distillation takes advantage of this idea. The distillation units ("stills") on, say, large naval ships, operate with a partial vacuum in the still to induce the water to boil (change state) at a lower temperature.
