Solute affects the freezing point of a solvent because, it hinders clustering of the solvent particles and forces the molecules away from the cluster. For the solvent molecules to reach the cluster and add themselves to the freezing solid, they have to be decreased to a lower kinetic energy by lowering the temperature

Arock can be broken down into different kinds of substances by physical processes. no chemical reactions are needed to separate different parts of a rock into pure substances. this is because a rock is a(n)

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.

Compare and contrast physical changes with chemical changes.
