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.
A gas is any matter that does not have a fixed shape or volume. Gases take the shape of their container and can expand or contract to change their volume. Plasma is matter that exists in the form of high energy charged particles. A phase change is a transition of matter from one state to another. Phase changes occur regularly in nature and can be conducted by people. The phase in which matter exists is determined by the pressure and temperature of its surroundings.
