  1. Al (an element)

  2. Pb (an element)

  3. Zn (an element)

  4. Fe (an element)

Place the materials in order form largest expansion to smallest expansion

https://demonstrations.wolfram.com/ThermalExpansionOfSolids/

  1. Pyrex (heat proof glass)

  2. Steel ( a mixture- alloy)

  3. Brass (a mixture - alloy)

  4. Glass (a mixture)

Why do you think that glassware that is designed to be heated in a lab is made out of pyrex instead of normal glass? (Note for the short answer questions you will not get a mark until I have had a look at your answers) (A single word answer will, however, always be worth 0 marks)!

From the simulation can we tell if alloys expand more or less than metal elements?
