Appendix-E of above article

The graph of Al, Fe,Sn & steel phase change temperature T in centigrad vs Time. The time axis is in what units hr, minutes, seconds or days?

. It's Not Waste: Teaching Recycling through Density, Phase Change and Solubility

The time axis is arbitrary because the time required for the phase changes will depend on the size of each sample and the rate that heat is applied.
