All substances take up the least amount of volume in their (1.) solid phase, a little more volume in their (2.) liquid phase, and the largest amount of volume in their (3.) gas phase. The closer atoms or molecules get to one another, the less volume is occupied by the substance that they comprise.

The average human can bite down with a 120 pound force. A grown up man can reach around 150. Itâs not a lot, but being bit by a human will still hurt and do damage. It is more difficult to measure the exact bite force of dogs, because they wonât bite as hard every time, and they will bite harder if theyâre provoked.
