Mrs. smith ordered a root beer float (vanilla ice cream + root beer). mrs. smith noticed that the three states of matter (solid, liquid, and gas) all existed simultaneously in her root beer float. a. identify each phase of matter in the root beer float. b. describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? ) c. identify one phase change you would see in a root beer float and described what causes this change.

How does the kinetic energy of a substance's particle in the solid phase compare to their kinetic enegy in the liquid phase?

If 125 cal of heat is applied to a 60.0-g piece of copper at 25.0 ? c , what will the final temperature be? the specific heat of copper is 0.0920 cal/(g? ? c) .
