Dear Scottie...
Please ignore my chemistry post...
Question- How much energy does it take to melt an ice cube?
Hypthesis- Since water has one of the highest specific heats out of any element, I predict that it will take over 10,000 joules to melt an ice cube.
Tools- Beaker, ice, water, iron mesh, propane burner, thermometer, beaker holder over fire thingy, styrofoam cup.
Controled/ independent/ dependent variables: Ice must start at the same temperature, and the water needs to come from the same source. The independent variables the mass, volume and temperature of the ice and water. The dependent variable is the energy needed to bring about these changes.
