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.
Matter changes state when more energy gets added to it. Energy is often added in the form of heat or pressure. So for this example the crayons are getting energy from the heat and this makes the crayons melt. Liquid molecules are looser and can move about easily. As the picture dries the crayons will become a solid again.
