A cube of ice is added to some hot water in a rigid, insulated container, which is then sealed. There is no heat exchange with the surroundings. What has happened to the total energy and the total entropy when the system reaches equilibrium?

Respuesta :

Answer:

Total energy decreases as well as total entropy.

Explanation:

Hello,

In this case, due to the effect of the high water's temperature, the ice will probably melt or at least, will decrease its initial temperature. In such a way, since no heat is exchanged with the surroundings, the system's equilibrium energy will be between the initial hot water's energy and the initial ice's energy, in other words, the total energy will decrease if the hot water's energy is larger than the ice's energy based on the first law of thermodynamics. Moreover, the total entropy of the system will decrease as long as during the aforesaid cooling process, the arrangement of system becomes less disordered (or more ordered) which is related with an entropy decrease, based on the second law of thermodynamics.

Best regards,

The total energy and the total entropy in the system reduces as the system reaches equilibrium.

Entropy and Enthalpy

Entropy is the degree of disorderliness in a system.

Entropy increases with temperature and vice versa.

Enthalpy is the sum total of the internal energy or heat content in a system.

The enthalpy of a system increases with temperature.

When ice is added to the system and allow to melt, the temperature of the system at equilibrium decreases as heat in used to melt the ice, thus, the energy and entropy of the system decreases.
