Answer with Explanation:
Density of copper(Cu)=
Density of zinc(Zn)=
Atomic mass of copper=
Atomic mass of zinc=65.38 g
We know that
Volume=
Using the formula
Volume of copper=
Volume of zinc=
Volume is inversely proportional to the density.
Pre -1982 penny made by copper and post-1982 penny made by zinc.
Therefore, volume of post-1982 penny is greater than the volume of pre-1982 penny because density of zinc is less than the density of copper.
Answer:
C.
Explanation:
Sublimation occurs when a substance changes from a solid into a gas. Increases in temperature causes the kinetic energy of particles to also increase.
since you didn't have solid to gas as a option liquid was the obvious choice
