Matter is defined as everything that has a place in space. All matter has two general properties - mass and volume. Mass is the quantity of matter and can be measured with a scale or balance in kilograms. Volume is the space a body occupies and can be measured with a graduated container in litres. Specific properties of matter include flexibility, fragility, resistance, rigidity, and whether something conducts or does not conduct heat.
