Answer 4

matter consisting of positively and negatively charged particles

Question 5

What happens to most matter when heated?

Answer 5

Most matter expands when heated

Question 6

Heat of Fusion

Answer 6

temperature change solid to liquid

Question 7

Heat of Vaporization

Answer 7

temperature change liquid to gas

Question 8

Boyle’s Law

Answer 8

decreased volume and hold temperature constant and pressure increases

Question 9

Example of Boyle’s Law
