WebThe specific heat capacity is the amount of heat it takes to change the temperature of one gram of substance by 1°C. So, we can now compare the specific heat capacity of a substance on a per gram bases. This value also depends on the nature of the chemical bonds in the substance, and its phase. q = mc Δ T, c = q ( J) m ( g) Δ T ( K) WebIn the equation ΔG = ΔH - TΔS: ΔH is positive. TΔS is positive, and so -TΔS is negative. Now increasing the temperature will change things. At higher temperatures, -TΔS will become more and more negative, and will eventually outweigh the effect of ΔH.
