Because the air pressure is lower, and the boiling point of water (and other liquids) decreases as the pressure decreases.
Water freezes at 0 degrees Celsius but temperatures can be even lower than the freezing point of water.
On top of a mountain
Yes, water will freeze below zero degrees Celsius. The freezing point of water is 0 degrees Celsius, but it can freeze at lower temperatures if the conditions are right.
Water is a solid when it's 0 degrees Celsius or lower and a liquid at 0 degrees Celsius or higher and when it is 100 degrees Celsius it turns in to a gas
More dense than what? I presume you mean is it more dense at that temperature than at lower temperatures. The answer is no, it gets denser at lower temperatures, all the way down to 4 degrees centigrade. Then it gets less dense again.
The vapor pressure of water at 10 degrees Celsius is lower than at 50 degrees Celsius. As temperature increases, so does the vapor pressure of water because more water molecules have enough energy to escape into the gas phase.
At higher altitudes, atmospheric pressure decreases, causing water to boil at a lower temperature. Near the top of a mountain, the reduced atmospheric pressure lowers the boiling point of water to below 100 degrees Celsius.

Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower at higher altitudes. This lower pressure decreases the boiling point of water. At sea level, the atmospheric pressure is greater, causing water to boil at 100 degrees Celsius.
Yes, a higher number in Celsius indicates a higher temperature compared to a lower Celsius number. Temperatures are measured using a scale where zero degrees is the freezing point of water and 100 degrees is the boiling point of water.
I didn't know it did. I don't think so.
