... Heat Capa Experiments in Physics indicate that the change in a body’s internal energy is directly proportional to the subsequent change in temperature, that is, ∆U α ∆T. As such, the physical quantity known as heat capacity, C, would be given by:
C = limit(∆T 0)( ∆U/∆T).
Therefore, heat capacity, also referred to as thermal capacity, is defined as the amount or quantity of heat or thermal energy needed to raise a body’s temperature by a single unit of temperature (Hewitt, Suchocki, & Hewitt, 2012). Thus:
C = Q/∆T
where Q is the heat energy and ∆T is the temperature change.
From this definition, the derived SI unit for heat capacity is Joule per Kelvin, JK-1.
According to Hewitt et al. (2012), t...
