Review Convection Notes As needed - Periods 6, 7

  1. Convection is the movement of thermal energy by the flow of material in a fluid.

    • Fluids are liquids or gasses.

    • when the particles of a fluid move from one place to another, they carry their thermal eenrgy alogn with them.

  2. Convection occurs Because of changes in density.

  3. When a fluid is heated, its particles move faster and spread out.

    • This causes the fluid to becoem less dense where it is ehated.

    • Less dense fluids are buoyant - so they rise.

  4. Where fluids cool, the particles slow down and contract.

    • This causes it to become more dense where cooling ocurs.

    • The dense, cooler fluid sinks.

  5. This rising and sinking can create a covection current

    • see digram below.

  6. Convection currents are found in a boiling pot of water as well as Earth’s atmosphere

Specific Heat Notes:

  • in notebook

  • review and modify

Specific Heat

  1. Specific heat measures how much thermal energy is needed to raise the temperature of an amount of a material by 1 degree.

  2. high specific heat means a material needs a lot of thermal energy to heat up

    • heats slowly

    • contains many enery units at a given temperature

    • water

  3. Low Specific Heat means a material needs relatively little thermal energy added to heat up.

    • heats up quickly

    • contains fewer units of thermal energy at a given temperature.

    • air

Thermal Expansion and Contraction

  1. Materials expand (grow) and contract(shrink) based on their temperature.

  2. When heated, particles move faster and spread out.

    • material expands

  3. When cooled, particles slow and become closer together.

    • material contracts.

  4. The thermal expansion/contraction of a material is a characteristic property.

  5. each material has its own rate of expansion/contraction

Finish Exploring Specific Heat.

If finished before peers, complete the Extension Activity attached to the assignment.

Extension Assignment -  Exploring Specific Heat 

For this activity you will use the PhET simulation titled Energy Forms and Changes.  Click this link to open it!

  • Follow these instructions, but do your work on the document you already completed.

  • Put it at the end of the document below question 15.

Steps

Review the work you completed on Exploring Specific Heat, items 1-15.

Open the simulation.

Brainstorm and consider ways to explore the specific heat of Brick and Iron.  You have samples of these included in the sim.  DO NOT USE the Energy Symbols option in your experiments!

Devise (create) two different experiments to help you infer which material has a higher specific heat. Complete your work for each experiment as follows:

    1. Describe your experiment and method.

    2. Make a data table and collect data from your experiment.

    3. Use the data to conclude which material has a higher specific heat.

      • Do steps a-c separately for each experiment.

      • Record this work on the Exploring Specific Heat worksheet under question 15.

Finally, check your work using the “Energy Symbols” and compare to what you concluded.
