Assuming a temperature of 30°C. it takes less energy to boil water on a mountain
than at sea level. Why does this occur?
There is more atmospheric pressure on a mountain than at sea level
It requires the same amount of energy
There is less atmospheric pressure on a mountain than at sea level
Water would not boil on a mountain
As elevation increases, atmospheric pressure decreases. This means that you'll need to supply less heat to the liquid water in order to get its vapor pressure to equal the atmospheric pressure.
