A cube of some rock weighs 6 grams, and a same-sized cube of water weighs 2 grams. What is the specific gravity of this rock?

The specific gravity of the rock with respect to water is equal to 3

Explanation:

To solve the question, we list out the variables as follows

Mass of rock = 6 grams

Mass of equal volume of water = 2 grams

Specific gravity or relative density is the mass of a unit volume of a substance divided by the mass of an equal volume of a reference material.

Specific gravity = (mass of substance)/(mass of equal volume of water)

Therefore the specific of the rock sample is = (mass of cube of rock sample)/(mass of same-sized cube of water)

= (6 grams)/(2 grams) = 3

The specific gravity of the rock = 3

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
