Objectives

Section 1: Temperature and Thermal Energy

• 1. Define Temperature

  2. Explain how thermal energy and temperature are related.

  3. Calculate the change in thermal energy of an object due to a temperature change.

Section 2: States of Matter

• 1. Describe the differences in the four states of matter.

  2. Explain how the motion of particles in a material changes at the material's melting point and boiling point.

  3. Explain why thermal expansion occurs.

Section 3: Transferring Thermal Energy

• 1. Compare and contrast the transfer of thermal energy by conduction, convection, and radiation.

  2. Compare and contrast thermal conductors and insulators.

  3. Explain how thermal insulators are used to control the transfer of thermal energy.

Section 4: Using Thermal Energy

• 1. Describe the first and second laws of thermodynamics.

  2. Explain how an internal combustion engine converts thermal energy to mechanical energy.

  3. Describe how the entropy of the universe changes when any event occurs.
