What is Charles’s Law?
Volume and Temperature have a direct relationship. As the temperature goes up, so does the volume, and vice versa.
What are the relationships of Boyle’s Law?
Volume and pressure have an indirect relationship-As the volume goes up, the temperature goes down, and vice versa
What happenes when matter freezes?(3steps)
A liquid turns into a solid.Energy decreases. Temperature decreases.
What is the freezing point?
0 degrees celsius
What is the boiling point?
100 degress celisius
What is the melting point?
0 degrees celsius
