Density

• Density is an intensive property, meaning it does not depend on the size or amount of the substance.
• To find out if an object will float or sink, compare its density with that of water (1000 kg/m3). If it's less dense than water, it floats; if more dense, it sinks.
• If two objects have different densities but are made up of the same material, they must differ in shape or size.
• Gas has low density compared to liquids and solids due to their large volumes relative to their masses.
• D = M/V

  M = D x V

  V = M/D
