Question

question 7 (multiple choice worth 1 point)
what property of water allows fish to survive in a lake that is frozen over?
high boiling point
low density as a solid
low vapor pressure
high heat capacity

Explanation:

When water freezes, it forms ice. Ice has a lower density than liquid water. This causes ice to float on the surface of the lake. As a result, the water below the ice remains liquid, providing a habitat for fish to survive. High boiling point refers to the temperature at which water turns to vapor, low vapor pressure is related to evaporation tendency, and high heat capacity is about heat - absorbing ability. None of these directly explain why fish survive under frozen lakes like low density as a solid does.

Answer:

Low density as a solid
