Question

Question 7 (2 points) The boiling point of water at sea level is 100 °C. At higher altitudes, the boiling point of water will be 1) higher, because there are fewer water molecules in the air. 2) lower, because temperatures are lower. 3) the same, because water always boils at 100 °C. 4) lower, because the atmospheric pressure is lower. 5) higher, because the altitude is greater.

          Question 7 (2 points)
The boiling point of water at sea level is 100 °C. At higher altitudes, the boiling point
of water will be
1) higher, because there are fewer water molecules in the air.
2) lower, because temperatures are lower.
3) the same, because water always boils at 100 °C.
4) lower, because the atmospheric pressure is lower.
5) higher, because the altitude is greater.
