For an object that is already a solid the change in its temperature does not affect its weight by any noticeable amount. The only change would result from the volume decrease as the object contracts when cooled. By occupying less space, it would displace less air and that would decrease the buoyancy of the object. That, though, would cause the object to weigh (slightly) more.
No.
Obviously frozen water. Its a solid after being frozen so it has become a solid. Actually it weighs the same I have conducted this experiment for my science fair and found that they weigh the same.
Less weight, imagine how much that would weigh if it was solid.
Frozen yogurt is a semi liquid/semi solid that is yogurt
They both weigh and cost less.
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.
Frozen solid change to liquid is a Physical change. melting
In a micro gravity, if the mass of each are equal they would 'weigh' the same.
we use scales to weigh solid
Fish will weigh less after it is thawed because it loses some water when it is thawed.
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)
Changing the temperature of something does not change its weight.
