Entropy is a measure of the amount of disorder or randomness in a system, indicating the system's tendency towards equilibrium.
Heat capacity is the amount of heat energy required to raise the temperature of a substance by a certain amount. It is a measure of how much heat a substance can absorb before its temperature changes.
- Entropy helps understand the behavior of systems in thermodynamics
- Heat capacity is crucial in determining the amount of energy needed for heating or cooling processes

Entropy is a measure of disorder or randomness in a system, while heat capacity is the amount of heat energy required to change the temperature of a substance. |
boltzmann constant
k_b
1 k_B = 1.380649e-23 m^2*kg/s^2/K (#5 of 7 SI Defining constants); The physical unit "k_b" is the Boltzmann constant, a fundamental constant in physics related to entropy and heat capacity. It is one of the seven SI defining constants. |
