for the proof of the helmholtz free energy question,
why is q smaller or equal to T(S2-S1)?
why is q smaller or equal to T(S2-S1)?
Helmholtz free energy, also known as Helmholtz energy or A energy, is a thermodynamic potential that measures the amount of work that can be extracted from a thermodynamic system at a constant temperature and volume.
Helmholtz free energy can be calculated using the equation A = U - TS, where A is the Helmholtz energy, U is the internal energy of the system, T is the temperature, and S is the entropy of the system.
Helmholtz free energy is significant because it provides a measure of the maximum amount of work that can be obtained from a thermodynamic system. It is also used to determine the equilibrium conditions of a system.
Helmholtz free energy is related to other thermodynamic potentials, such as Gibbs free energy and Enthalpy, through mathematical relationships. These relationships help to determine the equilibrium conditions of a system.
Helmholtz free energy is useful in situations where the temperature and volume of a system are constant, such as in closed systems. It is also used in the study of chemical reactions and phase transitions.
