The denser an object, the more compact it is. the table below shows the mass and volume of two different objects. comparison of liquids liquid mass (g) volume (cm3) x 72 12 y 63 9 which of the two objects is more compact a object x is more compact. b object y is more compact. c both objects are equally compact. d this cannot be determined. 2 problem the table below shows some physical properties of two unknown samples. physical properties sample mass boiling point x 100 g 56 °c y 290 g 56 °c what would best support whether the two samples are of the same substance or not? a the two substances are the same because their extensive property is different. b the two substances are not the same because their extensive property is the same. c the two substances are the same because their intensive property is the same. d the two substances are not the same because their intensive property is different.

PartA
 The first thing you should know to answer the question is the definition of density.
 Density is defined as the mass of an object between its volume.
 D = M / V
 Since we know that "The denser an object, the more compact it is" then we have to
 for object X
 D = (72g) / (12cm ^ 3) = 6g / cm ^ 3
 for the object and
 D = (63g) / (9cm ^ 3) = 7g / cm ^ 3
 therefore, the object y is more compact than the object x because its density is greater.
 answer
 b Object Y is more compact.

 Part B

 The first thing you should know to answer the question is the definition of intensive and extensive properties.
 The intensive properties are those that do not depend on the mass or the size of a body. Example: the temperature, the pressure, the speed, the specific volume (volume occupied by the unit of mass), the boiling point, the melting point.
 Extensive or Extensive Properties are those that depend on the quantity or size of a substance or body. Examples: mass, geometric volume, etc.
 Therefore, the two substances are the same since both have the same intensive property: boiling point 56 degrees.
 answer
 c The two substances are the same because their intensive property is the same.
