Does liquid water have mass?
Yes, liquid water does have mass. If you have one litre of water - then you have one kilogram of water (weight/mass). The same applies for if you have twenty litres of water... you then have twenty kilograms of water.
How are mass and energy conserved when water evaporates?
As the more energetic form of water -- water vapor -- is formed, the liquid water chills. Thus conservation of energy is preserved. Mass of course remains the same.
Are the volumes of water and ice the same?
The volume of a 100 milliliters of liquid water would be less if it were frozen. Water as ice (i.e. solid), is less dense than water as a liquid. The water would have the same mass whether solid or liquid, but its molecules occupy more space as a solid than they do as a liquid. This is a very unusual natural phenomenon, which is good for us or any frozen bodies of water would have all the life in it crushed by sinking ice!
Does a cup have the same amount of water after it has been frozen?
No. There are two main differences (and most others follow on from them): the temperature is lower so the frozen water is solid rather than liquid and the density has decreased (the same volume of water will have expanded).
How much does two pints of water weigh when frozen?
The same it weighed when it was liquid---but it has a greater volume because ice is "fluffier" than water.
What weighs less in space frozen or liquid water?
In a micro gravity, if the mass of each are equal they would 'weigh' the same.
How is the mass of frozen milk different from unfrozen milk?
A weighed unit of liquid milk has exactly the same mass as an equal unit by weight of frozen milk. However frozen milk has a lower density than liquid milk.
Why does the ice flaoats in the water?
Water is an unusual compound. When most substances freeze they contract. When liquid water freezes it expands. Density is mass divided by volume. You still have the same amount of matter, but frozen water it takes up a greater volume. Therefore, the density of frozen water is less than that of liquid water. So, it floats.
What did Antione Lavoiser discover?
Antione Lavoiser discovered that matter's form or shape can be changed, but its mass will stay the same. So the most common example would be: when boiling water, you will see steam rising from the pot, and you will notice the water level in the pot lowering. That water is changing its form to steam, but that steam has the same mass as when it was water in the pot. The same goes for when water is frozen into ice. The ice cube has the same mass as when it was in its liquid state before being frozen.
Why does ice stay over the liquid water on ponds and lakes?
When water is frozen, it expands, so ice has a greater volume than water. Also, since density is the volume of an object divided by its mass, and since ice has the same mass

What causes ice to float in liquid water?
When water is frozen, it expands, so ice has a greater volume than water. Also, since density is the volume of an object divided by its mass, and since ice has the same mass as water, the density of ice is slightly less than water, causing it to float on water.
Do all solids have less volume than same mass of liquid?
No. Water ice for example will have a larger volume than an equal mass of liquid water.
Describe how liquid water and ice affects rocks?
When water is frozen, it expands, so ice has a greater volume than water. Also, since density is the volume of an object divided by its mass, and since ice has the same mass as water, the density of ice is slightly less than water, causing it to float on water.
