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? Before you can even really answer the general question, you have to consider what type of wedding band or wedding ring that you are looking at.
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.
Another important physical property of matter is phase. The three most common phases of matter are solids, liquids, and gases. Water can exist in the solid, liquid, or gas phase. Most substances can exist in different phases. Changes in phase are also physical changes. For example, the physical properties of ice and steam are quite different but they are both water. There is no change in the chemical nature of the two substances.
