To decide whether the same method can be used to measure the specific heat capacity of a sample, the following factors that affect measurement during thermal diffusivity tests need to be analyzed: 1  Rise in temperature. 2  Laser pulse magnitude. 3  Reflection by other media. 4  Sample-related problems.
