The video tutorial covers calculations involving heat transfer without chemical or phase changes. It includes two example problems: one calculating the heat needed to raise the temperature of water, and another determining the temperature change when heat is added to a material. The tutorial explains the use of the equation Q = MCΔT, detailing how to identify known and unknown variables, rearrange the equation if necessary, and ensure units cancel correctly to find the solution.
