mL, L, KLUnits for a liquid's volume
1000 m1 Km
100 cm0.1 m
10 kg10,000 g
Density =Mass / Volume
Mass =Density x Volume
Volume =Density / Mass
An object will sink if the object's density isBIGGER than the density of the liquid
An object will FLOAT if the object's density isSMALLER than the density of the liquid
Matterthe "amount of stuff"
DensityHow packed together are the molecules
Exothermic ReactionEnergy or heat is released
Endothermic ReactionEnergy or heat is absorbed
The mass of the reactants must equal the mass of the productsLaw of the Conservation of Mass
