Water expands slightly when if freezes (due to hydrogen bonding) and the resulting ice is less dense than water.(Actually, the water still weighs the same- it just takes up more space when frozen)
yes!
No, just because a human is in water, doesn't mean they will weigh less. Humans would weight the same if they were in pudding, so humans do not weigh less in water.
Float
because there is less gravity in water
yes because the size of the molecules change therefore so does the weightCounterpoint:No, a gallon of water would weigh the same if it were frozen into a "gallon" of ice. The molecules do not change size, they simply do not move as fast and stick together when they are frozen. Therefore nothing is added or subtracted at a molecular level, and the weight of a liquid is the same whether it is frozen or solid.Water has a density of 1.00 gram/cubic centimeter.Ice, on the other hand, has a density of 0.931 gram/cubic centimeter.(As the volume is equal, and mass = density x volume)[Water will be heavier.]
No.
In a micro gravity, if the mass of each are equal they would 'weigh' the same.
yes!
It will still weigh one pound. The only thing that will change is its' size since it will expand by 9% and will become less dense.
If you mean *exactly* one cup by volume, you have the iceberg scenario. The cup of frozen water will be less dense, so it will weigh less. If you just freeze a cup of water, don't spill any, and *don't* trim the excess to bring the volume back to exactly one cup, then it will weigh exactly what it did at room temp.
Fish will weigh less after it is thawed because it loses some water when it is thawed.
Water will stay the same weight when it is frozen, it still has the same molecules that it started with
Yes, because the water that is frozen inside the pea is heavier and harder that a cooked pea, which has less water in it. If you just compare a package of uncooked and cooked peas, you'll feel the difference.
They weigh the same
No, just because a human is in water, doesn't mean they will weigh less. Humans would weight the same if they were in pudding, so humans do not weigh less in water.
Objects under water seem to weigh less but they have the same mass as they would out of water.
A bit less than 2% of the worlds water is frozen. Antarctica accounts for about 80% of the worlds fresh water.
