14. Endothermic vs. Exothermic
System that absorbs energy/heat from its surrounding
Phase Changes: melting, sublimation, vaporization
Exothermic
System that releases energy/heat to its surrounding
Phase Changes: freezing, condensation, deposition

15. Temperature Indicators
Boiling Point
When liquid goes to a gas
100ºC for water
Freezing Point
When liquid goes to a solid
0ºC for water

16. Evaporation or Boiling --Vaporization can be evaporation or boiling
Liquid to gas
At temperatures above the boiling point
At the bottom
Liquid to gas
At temperatures below the boiling point
At the surface

17. Lab Time

18. Exit Ticket
How can we tell the difference between evaporation and boiling?
In an endothermic reaction, heat is ___________.

19. Bell Ringer
What do you think heat is?
How is it transferred?

20. END DAY TWO

21. What is Heat?
Heat is the transfer of thermal energy from one object to another because of a temperature difference.
Most objects expand when exposed to heat
Flows from hot objects to cold objects

22. What is Temperature?
Measure of how hot or cold an object is compared to a reference point.
As temperature increases, the particles move faster
Instrument: THERMOMETER
Measures thermal expansion

23. Thermal Energy
Total potential and Kinetic energy of all the particles in an object.
Depends on the mass, temperature and phase of an object.
As temperature rises, thermal energy rises too.

24. How do you think heat is transferred? Activity Time

25. Conduction
The transfer of thermal energy with no overall transfer of matter.
Objects are touching
Conduction occurs in solids, liquids, and gases.
EX: Touching a hot metal spoon

26. Convection
Transfer of thermal energy when particles of a fluid move from one place to another.
Usually in liquids and gases because they flow easy
Ex: boiling water

27. Radiation Transfer of energy by waves moving through space.
All objects radiate energy
As temperature increases, the radiate energy increases
Ex: The Sun

28. Now let’s watch this!
Bill Nye the Science Guy - Heat

29. Exit Ticket What are the three ways energy is transferred?
Give an example of each. Try to come up with an example we didn’t talk about.
Heat flows from _______ to ________.

30. End of Day Three

31. Bell Ringer Explain the three mechanisms for heat transfer.
Give an example of each.

32. Specific Heat
The amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
The lower a material’s specific heat, the more its temperature rises when a given amount of energy is absorbed by a given mass

33. Heat of ______ of water Fusion Solid to liquid 334 J/g Vaporization
Liquid to gas
2260 J/g

34. Calorimeter An instrument used to measure changes in thermal energy
Uses the principle that heat flows from HOT to COLD

35. Conductors vs. Insulators
Materials that conducts thermal energy well.
Ex:
wire rack in an oven
Pots and pans
Insulators
A material that conducts thermal energy poorly.
Ex:
Wooden spoon
Air
