Answer:
Temperature stays constant.
Explanation:
During a phase change, the temperature does not change. Temperature will only change when a phase change is completed.
Basically, a voltaic cell usually works through a conversion of energy inside the system. Chemical energy is being converted to electrical energy through these specialised cells. In addition to that, a voltaic cell primarily consists of cathodes and anodes wherein reduction takes place in the cathode while oxidation in the anode.
Explanation:
The given data is as follows.
Mass of refrigerant, m = 10 kg
Volume of the refrigerant, V = 1.595
Formula for specific volume of the refrigerant is as follows.
v =
= 0.1595
So, at specific volume will be within and and pressure is constant.
The fluid will be in super-heated state at temperature and at T = pressure 1 bar = 0.1 MPa.
According to super-heated tables, the specific volume is v = 0.30138 .
Hence, the final volume will be calculated as follows.
=
= 3.0138
Thus, we can conclude that final volume of the R-134a is 3.0138 .
89.1% Au
The molar mass of Au2O3 is 2(196.97) + 3(16.00) = 441.94 g/mol
The mass percent of Au is therefore 2(196.97) / 441.94, which is 393.94/441.94 = 0.891 —> 89.1%
