Today Drew, Josh and myself (Jessie) did an experiment with particles where we heated a ball and ring with a Bunsen burner on a blue flame. We experimented by heating one at a time then cooling them, then heating both at the same time (Josh and myself tried to get them stuck but it didn't work) Drew unfortunately didn't do much because of his broken finger.
Here is a small list of items we used
-A ball and ring made out if brass.
-A Bunsen burner
-A heat proof mat
What happened ?
As we heated up the brass ball first we noticed it started to expand, and didn't fit through the ring anymore but when, when we heated the ring it also expanded and then the ball, fit through the ring once again. we also noticed that the colour changed from gold to a bronze type colour when heated and when cooled, it turned gold again.
