Why does water boil below 100 degree celsius at hill station

because liquid boils when its internal pressure of bubbles becomes equal to the external or environmental pressure. ... This is also why underwater geothermal vents can heat water to well over 700 degrees so the pressure down there is so high.I HOPE YOU UNDERSTAND

Heya mate...
The higher the pressure, the higher boiling point of water. At lower the pressure, the boiling point of water comes down. So, the lower pressure increases the boiling resulting more evaporation. As we go higher in altitude, the atmospheric pressure decreases. This results in decreasing the boiling point at higher altitude and increase in boiling of water. In fact, at the sea level ,the the sea water boils at 100 degree C where atmospheric pressure is normal. However , the boiling takes place at a lower temperature at the top of a mountain due to low pressure. In other words the boiling is faster at the top of a mountain than that at its foot.
hope it helps
