Web7 sep. 2012 · I think I need the specific heat of glucose (which I haven't found yet), but also I don't know why they give me the heat released by 1 mole of glucose. I need to know the method of how to solve such problems. physical-chemistry; thermodynamics; Share. Improve this question. Web30 apr. 2024 · 6 I have seen the equation S ( T 2) = S ( T 1) + C p ln ( T 2 / T 1) where C p is the molar heat capacity at a constant pressure. I understand that this assumes that the temperature range is sufficiently small that the constant pressure heat capacity does not vary significantly over it. My question pertains to the derivation of this expression.
Web22 sep. 2024 · The specific heat capacitance is the heat capacitance per gram of a substance. This value depends on the nature of the chemical bonds in the substance, and its phase. q = mcΔT or c = q(J) m(g)ΔT(K) Note: Capital " C " is the Heat Capacity of an object, lower case " c " is the specific heat capacity of a substance.
