What is the relationship between the Gibbs energy and chemical potential for a pure phase? How does the Gibbs energy of A(solution) Compare to Gibbs energy of Apure liquid)? How does the Gibbs energy of B(solution) COmpare to Gibbs energy of B(pure liquid)? d. When B is added to pure A, what happens to the Gibbs energy of A? e. Why does the Gibbs energy of the solvent of an ideal solution (in this case, A) decrease upon the addition of а. b. c.

2. The three types of radioactive emissions are called alpha (a), beta (B) and gamma (y) radiation. Complete the table below with the correct information about each type. Charge Atomic Symbol Can Be Stopped By Alpha Beta Gamma

1) For work done in an isobaric process, there is 2 equations equal to each other to find the answer (seen from the photo) but as I used those 2 equations I got 2 different values. Can someone help? 2) There is a phase change from solid to liquid which is isothermal. However, is it also an isobaric process? If not, what is the pressure at the solid state?

Two streams are mixed in an adiabatic mixer, as shown in the figure. It is known that: • Stream 1 is saturated liquid/saturated vapour mixture at 1 bar with flow rate 1.17 kg/s and quality 0.20 • Stream 2 is superheated vapour at 1 bar and 470°C • Stream 3, the product stream, is a saturated liquid/saturated vapour mixture at 1 bar with quality 0.89 Neglect kinetic and potential energy changes and calculate the mass flow rate of the superheated vapour stream, in kg/s.
