Temperature Change and Phase Change - Specific Heat and Latent Heat - From COLD ICE to Warm Water The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat which depends on the material and phase (for exmample, water and ice have different specific heat). The specific heat...

An experiment is performed on an unknown material and produces the following heat curve. The temperature of the material is shown as a function of heat added. If the sample of material has a mass of m- 9.20 g, calculate the specific heat when this material is a solid, Cs, and when it is liquid, q. (Please see the hint panel for the explicit temperatures of fusion and vaporization, do not try to approximate from the graph.) Temperature (Celsius) 550...
