Answer:
The final volume of the sample of gas = 0.000151
Explanation:
Initial volume = 200 ml = 0.0002
Initial temperature = 296 K
Initial pressure = 101.3 K pa
Final temperature = 336 K
Final pressure = K pa
Relation between P , V & T is given by
Put all the values in the above equation we get
= 0.000151
This is the final volume of the sample of gas.
Answer:
Explanation:
Hello!
In this case, given the initial conditions, we first use the 10-% quality to compute the initial entropy:
Now the entropy at the final state given the new 40-% quality:
Next step is to compute the mass of steam given the specific volume of steam at 175 kPa and the 10% quality:
Then, we can write the entropy balance:
Whereas sfg stands for the entropy of the leaving steam to hold the pressure at 150 kPa and must be greater than 0; thus we plug in:
Which is such minimum entropy change of the heat-supplying source.
Best regards!
The equation is already balanced so the mole ratio is just 1/1 and from the question you could conclude that the equation is a single displacement
