Answer:
0.4912 kJ/K
Explanation:
Using steam table, the properties of water at stage 1 can be determined:
= 400 kPa
= 60°C
Therefore, from steam table:
specific volume 
entropy 
Calculating the specific volume of water after the partition is removed, since the mass is constant and volume of water is doubled:
Final pressure of water in the tank = 
dryness factor after removing the partition
Therefore:
Thus, the entropy change is:
Δs = 
Therefore, the entropy change of water is 0.4912 kJ/K
Suppose the gas is ideal gas. According to the ideal gas equation of state, pV = nRT, the pressure is unchanged. So Vi/Ti = nR/p = Vn/Tn. (i stands for initial and n stands for new) So the new volume Vn = 3.67 L
Answer:
Electrons are always marked negative Hence electronic energy is also always taken as negative. It is because when an electron is at infinite distance from nucleus , there the kinetic energy of that electron can not be calculated. So, it is taken to be zero . ... And thus the energy of electron becomes less negative
Your independent variable would be salt because it doesn't change the only thing that changes is the water.
