Pyrex (heat proof glass)
Brass (a mixture - alloy)
Glass (a mixture)
Steel ( a mixture- alloy)

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?
(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 metals expand more than non metals?
(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)!
