Matter cannot be created nor destroyed, The number of atoms/mass of the reactants equals the number of atoms/mass of the products.

• solid, liquid, and gas • Changed by changing temperature or pressure

• Definite shape & definite volume • Particles packed together and vibrate but have fixed positions • Lower energy

• No definite shape but has definite volume • Particles spread apart • Medium energy

• No definite shape & no definite volume • Particles spread far apart • High energy
