Cooling curve practical

WebSimilarly, the drop in temperature due to cooling in the time interval between t 1 and t 2, is given by Δt 2 = KA 1. (Note that, since the mechanism by which cooling takes place is the same for times between t 1 and t 2 and between t 2 and t 3, the constant of proportionality will be the same for both regions.) So ΔT 2 ΔT 3 = A 1 A 2 WebExperiment #1: The Cooling Curve of Stearic Acid INTRODUCTION Matter around us exists in three common states-solid, liquid, and gas. Matter can change from one state (or phase, as it is sometimes called) to another. Ice, for example, is the solid state of H 2O. Add energy, and the rigid solid structure breaks down to the liquid state, water.
