Careful, precise and complete reasoning is needed for all items. Physical properties are classified into two categories: extrinsic and intrinsic. Extrinsic properties are general and apply to all substances where intrinsic properties are specific to each substance. Characteristic properties of substances are all intrinsic properties. Use this information to answer the following questions. 1) Explain why the mass of a sample is not an intricsic property of a substance, but the mass of the particles making up the substance is. 2) Explain why temperature is not an intrinsic property, but melting point-which is a temperature is an intrinsic property. 3) How can density be an intrinsic property when mass and volume individually are not? 4) Explain why two samples having the same mass tiny particles does not necessarily mean that the two samples are the same substance. 5) Explain how two different substances can have the same value for an intrinsic property such as viscosity (how readily a liquid flows).
