What is the change in entropy of 250 g of steam at 100 ∘c when it is condensed to water at 100 ∘c?

Sagot :

Entropy change is the randomness of the thermodynamic system. The change in the entropy when the water is condensed is 1573 J/K.

What is the entropy change?

An entropy change is a product of mass and the ratio of the enthalpy of vaporization to the temperature.

Given,

Enthalpy of vapourization =  2257 J/gK

The temperature in kelvin = 373 k

The change in entropy is calculated as:

[tex]\begin{aligned} \rm \Delta S &= \rm m (\dfrac{\Delta H_{vap}}{T})\\\\&= 260 (\dfrac{2257}{373})\\\\&= 1573.24\;\rm J/K\end{aligned}[/tex]

Therefore, the change in entropy is 1574 J/K.
