Here are some things I have learned about matter and energy while attending college for hvac/r.
*Matter is a substance that takes up space and has a weight
*The density of a substance tells us its mass-to-volume relationship
*An example of fossil fuel is natural gas
*There are 746 watts of electrical power in 1 horsepower
*Gas molecules travel in a downward, upward, and sideways direction
*The only new energy we get is from the sun
*The law of conservation of energy states that Energy can neither be created nor destroyed but it can be converted from one form to another
*Work is equal to force x distance
*Matter can be either be a solid, liquid,or a gas.
