Graph represents the sea-level heating curve of water. how would the boiling point be represented in a new, high-altitude heating curve? a) there would be no boiling point on the graph; water does not boil at high altitudes. b) the boiling point would be lower; water boils at lower temperatures at high altitudes. c) the boiling point would be higher; water boils at higher temperatures at high altitudes. d) the boiling point would be represented as a diagonal line; water has no exact boiling point at very high altitudes.
