True or false cleavage and fracture refer to the same way in which a mineral breaks

the do not break in the same way so false

Explanation:

Fracture and cleavage both describe how a mineral breaks. Fracture refers to rough or irregular surfaces along which the mineral breaks randomly. Cleavage refers to flat planes along which some minerals break.

a. autosomal.

explanation:

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
