What is the reason for water boiling at a lower temperature at high altitudes?
Because the atmospheric pressure is higher
Because the water is purer
Because the atmospheric pressure is lower
Because of the presence of salt
What happens to the boiling point of water when salt is added?
It decreases
It remains the same
It increases
It becomes unpredictable
When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it

Surface Tension
Cohesion
Adhesion
Density
