Answer;
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.

Answer:
Air speed of bird is
mph
Explanation:
let the speed of the bird in still air be "X"
Speed of the bird when it flies in the direction of flow of wind 
Speed of the bird when it flies in the opposite direction of flow of wind 
The total time taken is equal to
minutes
hours
The distance in miles is equal to
miles

On solving the above equation, we get -

Air speed of bird is
mph
