- 1. 6 th Grade Science Chapter 18 Thermal Energy Notes Section 18.1 Chihuly at the New York Botanical Garden
- 2. <ul><li>What is temperature? </li></ul><ul><li>Temperature is a measure of the average value of the kinetic energy of the molecules in an object. </li></ul><ul><li>What is thermal expansion? </li></ul><ul><li>Almost all objects expand when they are heated and contract when they are cooled. </li></ul>Key Questions 1
- 3. <ul><li>The higher the temperature, the faster the molecules are moving. </li></ul>Temperature
- 6. <ul><li>When the temperature of an object is increased, its molecules speed up and tend to move farther apart. </li></ul>Thermal Expansion <ul><li>This causes the object to expand. </li></ul>
- 7. The photograph to the left shows railroad tracks distorted because of thermal expansion on a very hot July day. The photograph is from Halliday, Resnick and Walker, Fundamentals of Physics
- 9. <ul><li>What are the freezing and boiling temperatures of water in the Fahrenheit scale? </li></ul><ul><li>Water freezes at 32 0 F and boils at 212 0 F. </li></ul><ul><li>What are the freezing and boiling temperatures of water in the Celsius scale? </li></ul><ul><li>Water freezes at 0 0 C and boils at 100 0 C. </li></ul>Key Questions 2 The Tadpole Galaxy
- 11. <ul><li>To be able to give a number for the temperature, a thermometer has to have a temperature scale. </li></ul>Temperature Scales <ul><li>Two common temperature scales are the Fahrenheit and Celsius scales. </li></ul>
- 13. <ul><li>What is the conversion equation to convert temperature in 0 Fahrenheit to 0 Celsius? </li></ul><ul><li>To convert temperature in 0 F to 0 C: 0 C = (5/9)( 0 F-32). </li></ul><ul><li>What is the conversion equation to convert temperature in 0 Celsius to 0 Fahrenheit? </li></ul><ul><li>To convert temperature in 0 C to 0 F: 0 F = (9/5)( 0 C) + 32. </li></ul>Key Questions 3 The Sombrero Galaxy
- 18. Iceberg off Canadian shore.
- 19. <ul><li>What is the conversion equation to convert temperature in 0 Celsius to 0 Kelvin? </li></ul><ul><li>To convert temperature in 0 C to 0 K: 0 K = 0 C+ 273. </li></ul><ul><li>What is the thermal energy of an object? </li></ul><ul><li>The thermal energy of an object is the sum of the kinetic and potential energy of all the molecules in an object. </li></ul>Key Questions 4
- 20. <ul><li>Temperature and thermal energy are different. </li></ul>Increasing Thermal Energy <ul><li>Suppose you have two glasses filled with the same amount of milk, and at the same temperature. </li></ul><ul><li>If you pour both glasses of milk into a pitcher, the temperature of the milk won’t change. </li></ul>
- 21. Glass is brought to its melting point of 2400 0 F
- 24. <ul><li>Explain the difference between temperature and thermal energy. How are they related? </li></ul><ul><li>Determine which temperature is always larger- an object’s Celsius temperature or its Kelvin temperature. </li></ul><ul><li>Explain how kinetic energy and thermal energy are related. </li></ul><ul><li>Describe how a thermometer uses the thermal expansion of a material to measure temperature. </li></ul>Questions Section 18.1
