No, there is a huge variation in size. DNA and protein molecules are relatively huge. Water and oxygen molecules are quite small. Hydrogen is the smallest.
During a phase change, the arrangement of molecules changes while their size remains the same. For example, when a solid transitions to a liquid, the molecules rearrange into a more disordered state, but their actual size does not change.
Proteins do it all the time, its called folding.
It is an element
No.
No
No. molecules are smaller.
A calorie is a measurement of energy and has no size.
They relate because they have the same shape and size.
No, all plates are not the same size
the sponge has less molecules where as the book has more molecules in one place

are all nuclei the same size( diameter
No. All of a square's sides are the same size.
No they do not.
Water and Moisture (water vapor) are the same molecules, just in different physical states. It's all water, so the molecular sizes are the same.
Nope, All molecules are different. They might look the same, but they aleast have thing different.
No, they are not all the same.
