Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

A food product containing 85% moisture content is being frozen. Estimate the specific heat of the product at -4 ° C when 62% of the water is frozen. The specific heat of the dry product is 2.5 kJ / (kg ° C). it is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and the specific heat of ice follows the function Cp es = 0.0062 Tfrozen + 2.0649. Cp of frozen product = kJ / kg ° C.
Using 1st and 2nd law of thermodynamics for irreversible expansion of Krypton: Krypton (ideal monatomic gas) is confined in one-fourth of a 48-litre container. The other part of the container is evacuated. When the partition is removed, the gas expands and fills the whole container, while the system loses 400J of heat to the environment at 290K. It is found that in the final state, the Krypton is at p2 = 5.5bar, T2 = 400K. Is this process possible or not? (?k?????? = 83.8 kg/kmol)
