WebMelting point: 0 degrees C At higher altitudes, air pressure is lower. When the pressure is lower, it takes less energy to bring water to a boil, less energy means less heat so water boils at a lower temperature at a higher altitude. In freezing and melting points, there is a very slight difference but it is unidentifiable in this experiment. WebWe would like to show you a description here but the site won’t allow us.
