Week 10: Properties of Water

Question 7 • *STPSB_Environmental Science 2627

Which unusual properties are a result of water’s hydrogen bonding? Check all that apply.

Answer
A
high boiling point
B
high specific heat
C
higher density as a solid than as a liquid.
D
high surface tension

Explanation

Hydrogen bonds take energy to break, so water has a high boiling point and a high specific heat. They also create strong cohesion between water molecules at the surface, giving water high surface tension. Ice is less dense than liquid water, so choice C describes the opposite of water’s unusual density behavior.
