Question

How does the formation of ice in the freezing compartment of a

refrigerator demonstrate the particulate nature of matter?

A. As the particle energy of matter decreases, the motion of the atoms in a

given space decreases

B. As the particle energy of matter decreases, the motion of atoms in a given

space increases

C. As the particle energy of matter increases, the motion of atoms in a given

space decreases

D. As the particle energy of matter increases, the motion of atoms remains

unchanged

Answer 1

Answer:

The correct option is A

Explanation:

Generally, when the temperature of matter is low and starts to cool, the kinetic energy of it's particles decreases which causes the motion of the atoms within it's particles to also decrease. When the kinetic energy of the particles decreases, it causes the matter to form a mass by coming together since it's atoms will no longer be able to move freely as before (just like in solids) - this is the reason for the formation of ice in the freezing compartment.

From the explanation above, it can be deduced that the correct option is A
