Calculate ΔS for the isothermal compression of 3.05 mol of Cu(s) from 1.00 bar to 1370. bar at 298 K. α=0.492×10−4K−1,κT=0.78×10−6 bar−1, and the density is 8.92 g⋅cm−3.

Explanation:

For compression, equation for entropy change () is as follows.

              =  

Hence, for an isothermal process

Now, we will put the given values into the above formula as follows.

           =            = -0.146 J/K

Thus, we can conclude that value of for the isothermal compression is -0.146 J/K.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
