Carmen is heating some water and trying to measure the temperature of water using a celsius thermometer. which measurement can she expect once the water begins to boil?

The pure water boils at 100°C. So she should measure a value around this. But the boiling point also depends on the barometric pressure and the "pureness" of the water. So if for example, she is in a place with low pressure, such as a high mountain, the water will boil at a temperature less than 100°C.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
