Water has lower boiling point at the top of the mountain because

temperature of the air at high altitude is lower.

Density of the air at high altitude is lower.

gravity at higher altitude is lower

Number of the particle inside the water decrease at higher altitude.

3. Diagram below shows a syphon used to remove dirty water from an aquarium. Which one is correct when the water flow out through the tube?

A. The pressure in the tube is higher than the pressure of atmospheric pressure.

B. The position at the end of the tube outside of the aquarium must be higher than the position of the end of the tube inside the aquarium.

C. Pressure inside the tube is lower than atmospheric pressure

D. When the water level inside the aquarium decrease, the speed of the water flow out is increase.
