The plan up to Thanksgiving.

Thursday(tomorrow)-- finish going over "What is Heat?" assignment. Students have a quiz over the two chapters. Students should focus on vocabulary.

Friday--in-class activity to reinforce different types of heat transfer (conduction, convection, radiation)

Monday--Chapter Review from green Study Guide handed out today. p. 168-172 (omit 23-26) needs to be complete.

Tuesday--Test over "Temperature" and "What is Heat?"

Temperature

SUMMARY

• Temperature is a measure of the average kinetic energy of the particles of a

substance.

• Fahrenheit, Celsius, and Kelvin are three temperature scales.

• Thermal expansion is the increase in volume of a substance due to an increase

in temperature.

• Absolute zero (0 K, or –273°C) is the lowest possible temperature.

• A material may be chosen for a particular purpose because of the way it

responds to heat or cold.

• Some materials, such as metals, conduct energy well.

• Some materials, such as air or ceramics, do not conduct energy well.

VOCABULARY

1. temperature

2. thermal expansion

3. absolute zero

4. expand

5. contract

What is Heat?

SUMMARY

Heat is energy transferred between objects that are at different temperatures.

• Thermal energy is the total kinetic energy of the particles that make up a substance.

• Thermal energy will always be transferred from higher to lower temperature.

• Transfer of thermal energy ends when two objects that are in contact are at the same temperature.

• Conduction, convection, and radiation are three ways thermal energy is transferred.

• Specific heat is the amount of energy needed to change the temperature of 1 kg of a substance by 1°C.

• Energy transferred by heat cannot be measured directly. It must be calculated using specific heat, mass, and change in temperature.
