The required entropy change can be calculated along a process in which the water is heated from $T_{1}$ to $T_{2}$ and then allowed to evaporate. The entropy change for this is $$ \Delta S=C_{p} \ln \frac{T_{2}}{T_{1}}+\frac{q M}{T_{2}} $$ where $q=$ specific latent heat of vaporization.

The Intel A P is provided as 20.91 Hello, Jules Caramel. It will be equal in tow. 30.91 mile deep pretenders to part three jewels. Permal the entropy is given us 93.2 Jules per kelvin. Morning. The boiling point be will be Delta H, divided by Delta s substituting the value. We have 30.91 tenders to power three, divided by 93.2. The boiling point turned out to be 331.7 killed him, which is equally villain, too. 58.5 degree senses.

I have even so in this question they asked. The heat of vaporization of water is 43.9 kg per mobile And it's normal boiling point is 373 Kelvin estimate the vapor pressure of water at 351 Kelvin songs according to clauses. Clapper an equation according tools. Garcia's okay to let Iran the creation last great show. I learned off We two upon the U. N. That is equal to my nurse. No, that acts upon our when a bomb T 2 -1 of bond B one and therefore L. A. Now we to upon one that is inquiry to 43,900 jule upon I read 8.314 In cyber. Get one upon 351 -1 upon 373. And that is equal to that on a line up. He took up on one that is equal to minus zero point 8873 and therefore peter upon one. That is equality planes 412 and therefore it is equal to 412 It must be thanks

In this problem I will use the formula loan be to bip even is equal to. Imagine that bye. Our multiplication one by 8: -1 by even. So putting the value in this exhibition, I can write it as log 760 x 19 is equal to or did you know 6 7 year old by 2.303? Multiplication 8.3, multiplication 37 3-. Even by He won multiplication 37 3. Which on simplification I get developed even is equal to 291.4 Kelvin according to the given option. We can say that option B each correct answer option B each but it.

So we know that the entropy change delta S. Is calculated from the changing hit. That's delta Q. Divided by the temperature. So in this example the temperature's constant. We're looking at vaporization which happens a constant temperature so we can just plug in the value of delta Q. And T. And that will give us a change in entropy. If the temperature weren't constant, for example, um if it weren't a melting or uh boiling, we were just changing the temperature the same faith, we have to integrate to account for changing temperature. So not for this problem though, is that the constant temperature? The temperature's constant 100°C.. That's 3 73 Kelvin. And the mass of water involved is 10 g. That's .1 kg. Then my calculator, delta Q. Does the change in heat. And in this case that's the same as the heat of vaporization. So that's equal to the mass, multiplied by the latent heat of vaporization. So that's the number given in the question. 2257 killer jewels. So we multiply .01 with 2257. Yeah. And we get uh changing head Um they'll take you of 2-570 jewels. And next step is simply plug in the delta Q and divide by the temperature in Calvin's. And we get our final answer 60.5 joe's per kelvin of entropy.
