Do ice and water have the same volume and weight?

Question

i was wondering because whenever i freeze a water bottle it gets all roundish.......and when i open it when its still about half frozen the water squirts out like soda.........could it be that ice has more volume than water?

Answer 1

weight....yes

volume....no

Answer 2

H20 expands when it freezes so it has more volume. However, the amount of H20 remains the same. If you let it melt, the volume will return to what you had when you started. The mass will never change unless you add or subract water. Weight is dependant on gravity. Your bottle of water would weigh less on the moon.. but the volume would still be the same.

Answer 3

Volume expands in ice form, but the weight stays the same.

Answer 4

density= mass/volume

Most compounds increase in density as temperature decreases, but water is a special case. The density of ice is less than that of water because the volume is greater than that of water, yet the mass remains the same.

Water is most dense at 4 degrees celsius, as it gets colder, the ice crystals begin to form and the density decreases.

This simple concept is responsible for life as we know it. If ice were more dense than water, ice would sink to the bottom of a body of water and it would eventually accumulate and completely freeze solid.

Your observation is correct
