WebDec 3, 2016 · As T → 0 the spacing is greater than k T, and the end result is the solid has no accessible degrees of freedom and therefore a zero heat capacity. However the moment you add the smallest amount of heat the temperature increases, some states become accessible and the specific heat becomes non-zero. WebMay 20, 2024 · The direction of heat flow is not shown in heat = mc Δ T. If energy goes into an object, the total energy of the object increases, and the values of heat Δ T are positive. If energy is coming out of an object, the total energy of the object decreases, and the values of heat and Δ T are negative. Example 3.12.1 binary number system explained
