No.
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.
In a micro gravity, if the mass of each are equal they would 'weigh' the same.
Fish will weigh less after it is thawed because it loses some water when it is thawed.
I dont really know
A frozen turkey does not weigh more than fresh. A 15-lb frozen turkey will weigh 15 lbs. when it is thawed.
frozen food
No: different substances have different densities, so for a given volume, two different substances will generally weigh different amounts. A couple of examples should help illustrate this: ice floats in water as its density is low, whilst a lump of iron (effectively frozen liquid iron) would sink in water as its density is higher. If they were the same volume, the iron would weigh more.
Baby food in jars has no need to be frozen. Homemade prepared baby food can certainly be frozen.
18 degrees Fahrenheit is frozen food. 18 degrees Celsius is not frozen food.
you exersise and eat more greens and less junk food
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.
