If the object shown has a mass of 80g, what is the density?

C. 1.23 g/ml

Explanation:

Mass of rock = 80g

Volume of rock = final fluid volume - initial fluid volume

Volume of rock = 265 cm³ - 200 cm³ = 65 cm³

1 cm³ = 1 ml

Therefore, density of the object = 1.23 g/ml

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
