The video tutorial explains how to determine the final temperature of an ice-water mixture. It covers scenarios where only some of the ice melts and where all the ice melts, using energy balance equations. The tutorial includes detailed calculations of energy changes for both ice and water, considering specific heat and enthalpy of fusion. A new problem with different quantities of ice and water is also solved to illustrate the concepts.
