Nov 21, 2023 · Heat capacity (C) is the amount of energy needed to raise the temperature of a specific substance by 1 degree Celsius. Heat capacity can also be viewed as the ratio of the amount of energy ...

Nov 21, 2023 · Specific heat capacity, or simply specific heat, is the amount of heat required to change the temperature of a substance. As water requires more time to boil than does alcohol, you might conclude ...

Jan 30, 2019 · The first thing you need to do is stop thinking about heat capacity in terms of heat Q. In thermodynamics, we define heat capacity in terms of internal energy U and enthalpy H, not in terms of heat. In this way, heat capacity is a physical property of the material being processed, and not a function of the process path.

Nov 21, 2023 · Heat capacity, C, however, refers to the specific amount of heat that can raise the temperature of a substance 1 degree C. Water has a high heat capacity of 4.184 J/g degree C.

Although John's answer is quite comprehensive, I would like to add this answer in order to reinforce my qualitative understanding of the matter and to try to provide the OP a more intuitive and qualitative explanation for the negative specific heat capacity as the OP seems to be looking for a more qualitative (and intuitive) sort of explanation.

Sep 14, 2016 · In freshman physics, we learned that, when heat is added to a constant volume system, we can write Q = mCΔT, where C is called the specific heat capacity. However, when we got more deeply into the basics and learned thermodynamics, we found that this elementary approach is no longer adequate (or precise).

Dec 12, 2017 · The SI unit is joule per kelvin per kilogram. For example, the heat to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1. Much of the above stolen from wikipedia. So if you add energy E to mass m, and the increase in temperature is T, then the specific heat capacity ...

Dec 3, 2016 · Zero heat capacity means an infinitesimally small amount of energy will increase the temperature by an infinitely large amount. An object has a non-zero heat capacity because it has internal degrees of freedom that it can channel absorbed energy into. The more internal degrees of freedom the higher the heat capacity.

Jun 11, 2021 · As Heat Capacity of solids has two contribution: One arising from lattice, called lattice heat capacity and another from electrons, called electronic heat capacity. At absolute zero, we say that heat capacity of solids is zero, which according to me implies that even a small amount of heat would increase the temperature by finite amount.

Nov 5, 2024 · So, for example, a monoatomic ideal gas has a heat capacity of $3k_B/2$ per atom since there are only three degrees of freedom (isochoric heat capacity, that is). Therefore the specific heat capacity is $3R/2$. In a solid, you have electronic and phononic contributions to the heat capacity, representing the different "modes" heat may be absorbed.
