This lesson

• Recap properties of matter
• Physical and chemical – intensive and extensive
• Solubility

Goals

• Recap what is coverd before carnaval

• Give examples for physical and chemical

• Create an overview for physical and chemical — intensive and extnsive.

• Answer the questions:

what is solubility? What is a solvent?  what is a solute?

What have we coverd before caranval?

What do you remember from before the carnaval break

What to points is a thermometer calibrated to?

How do you calibrate a liquid-in-glass thermometer to those two points?

• Capillary
  

• Liquid reservoir

• Thermometer liquid

• Scale divisions

Exercise

Draw the thermometer schematic in your notebook and place the words at the right spot with a line pointing to it.
