The table below shows some physical properties of two unknown samples. physical propertiessample mass freezing pointa 1000 ml 0 °cb 1000 ml −95 °cwhat would best support whether the two samples are of the same substance or not? a. the two substances are the same because their intensive property is same. b. the two substances are the same because their extensive property is different. c. the two substances are not the same because their extensive property is same. d. the two substances are not the same because their intensive property is different.

Extensive property is that which depends on the amount of matter in a sample. For example: mass, volume, size  are all extensive properties

Intensive properties are independent of the amount of matter. These include; boiling point, melting point, color and so on.

In the given examples:

Both sample A and B have the same volume (1000 ml) i.e. the same extensive property. However, they have different freezing points i.e. different intensive property.

Ans: D) The two substances are not the same because their intensive property is different.

b

explanation:

mitosis

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
