Intensive properties: These are those that do not depend on the mass of the sample.
Density is an intensive property. For example, the density of an ice cube and an iceberg is the same (0.92 g/cm3 at temperatures below 0°C at sea level), which is less than that of water (1.0 g/cm^3 , under a temperature of approximately 4°C and a pressure at sea level, which is equal to 1.0 atm). Therefore, both an ice cube and an iceberg float on water.
2. Extensive properties: These are those that depend on the mass (“extension”) of the sample.
So mass is an extensive property and length as well.
Answer:
Extensive physical properties: mass of 18.45 g and 3.50 cm in length
Intensive physical properties: Density of 2.70 g/cm^3
