When solid sodium hydroxide dissolves in water, δh for solution process is −44.4 kj/mol then final temperature of the solution is 23.758 °C
q=mc(T2-T1)
T2=q/mc+t1
T2= -44/13.9×4.18+23
T2=23.758 °C
Temperature is the unit used to describe heat or cold. It illustrates the natural flow of heat energy from a hotter to a cooler body and can be expressed in terms of a variety of arbitrary scales (one at a lower temperature). An iceberg has a much higher total heat energy than a match, despite the fact that a match burns at a much higher temperature. Temperature and a thermodynamic system's energy are not the same thing. In contrast to extensive features like mass or volume, such as temperature is referred to as an intense property—one that is independent of the amount of material being addressed—along with pressure, density, and other similar qualities.
