Section 10.2 Notes

The following 3 terms are important to know for section 10.2:

Temperature is the average energy of the moving particles of a solid, a liquid, or a gas

Thermal Energy is the total energy of the moving particles of a solid, a liquid, or a gas

Heat is the thermal energy transferred from an area of higher temperature to an area of lower temperature

This is the video we watched in class. Remember that we use the term "Thermal Energy" for the total amount of energy in a substance and this video refers to it as "heat". We are using the term "heat" when we refer to the transfer of thermal energy only.

Chapter Summary

• Solutions consist of solutes and solvents. • Solutions can be dilute or concentrated, and saturated, unsaturated, or supersaturated. • The concentration of a solution is the amount of solute dissolved in a specific amount of solvent.

• The concentration of a solution can be described in qualitative and quantitative terms. (8.1) • Solutes and solvents can be identified in various kinds of solutions. (8.1) • Solubility is affected by temperature, type of solute or solvent, particle size, and stirring. (8.2) • Solutions and mechanical mixtures are separated in different ways. (8.3) • Water is sometimes known as the universal solvent. (8.1) • Gases dissolve more in colder water than in warmer water • Water is sometimes known as the universal solvent.
