I recently noticed the following question in a blog post that I did for WeddingBands-WeddingRings.com in 2009 â How much does a wedding band or wedding ring weigh?

In physics, a state of matter is one of the distinct forms that matter takes on. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
In a physical change a new substance is not created. In a chemical change a new substance is created. This applies to changes in states of matter. For example, ice, waterâ¦, and steam are all the same substance, even though they exist in three different states. The elements of which they are comprised do not change.
