Verify concepts of phase equilibrium and phase transitions using the steam tables. a. Establish by direct calculation this equality between molar Gibbs free energies for steam at 2.5 MPa and 224oC : Gl = Gv
b. Calculate Gv at 2.5 MPa for temperatures between 225 and 400oC and extrapolate this curve below 224 oC.
c. Find Gl at 160, 170, 180, 190, 200, and 210 oC. Plot in the same graph used for part b and extrapolate above 224 oC. Hint: for a liquid, H and S can be taken as independent of P.
d. Plot the molar volume V vs. T at P =2.5 MPa over the T range between 150 and 400 oC, and show that V is discontinuous.
e. Plot Cp vs. T at P =2.5 MPa over the T range between 150 and 400 oC, and show that Cp is discontinuous.
f. Using the data in the steam tables, show that the Gibbs energies per unit mass of steam and liquid water in equilibrium at 300 oC are equal.

how is this a question? in order for me to answer it i have to understand the question

explanation:

answer:

all three have their own beauties

explanation:

it is difficult to choose someone as most beautiful

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
