Metals and Water

Last week in the science lab we tested seven different metals and see what their reaction is in water.

The metal that reacted the most was calcium.

The metals that reacted the least were Aluminum, steel wool and copper.

Did you know that the most common metals used in jewelry are bronze, gold and silver.

Bursting Water Experiment

   

We boiled water on a Bunsen burner and tested the temperature of the water when it boiled for 30 seconds, 60 seconds and 90 seconds. We also tested the temperature of the water when it wasn't boiled. When water wasn't boiled the temperature was 0.22. 

Water boils at 100℃ but other liquids can boil at different temperatures. 

Water cannot be boiled over 100℃ but at a critical temperature water can boil up to 374℃.
