We will really dive deeply into energy today. You will learn how to find the energy absorbed or released by a substance using specific heat and ways in which energy flows into and out of a system.

### Warm-Up

1. 1. Define each of the following in your own words:
1. a. Thermal energy
2. b. Mass energy (Kinetic energy)
3. c. Potential energy
4. d. Chemical energy
1. 2. Identify which form(s) of energy is/are changing in the scenarios below and indicate how they change (increasing or decreasing):
1. a. An acid and a base are mixed and the temperature of the solution increases.
2. b. A log burns in a fireplace.
3. c. A penny is dropped from the empire state building.
1. 3. ∆E=q+w

Identify the variables in this equation and explain how a car skidding to a stop could be represented using this equation.

### Objectives

• Use specific heat to determine the total amount of energy gained or lost by a substance
• Describe temperature vs. heat

### Homework

• Finish assignment 2.02 using MyOpenMath.
• Reflect on assignment 2.02 on teams
• Study for exam 1 (Thursday/Friday)
