What change of state occurs during vaporization?

Liquid to gas

Explanation:

When molecules are in the liquid state, they are held together by internal forces of the molecules while moving in a constant motion.Increasing the temperature through heating, will make the molecules move faster and collide at a higher rate because they gain kinetic energy after obtaining the heat.This will loosen the forces holding the molecules together leading to vaporazation.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
