Question- A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the final number of microstates is 0.448 times that of the initial number of microstates?
I just need a general explanation of it please- Thanks
How much work (in {\rm J}) is required to expand the volume of a pump from 0.0 {\rm L} to 2.6 L against an external pressure of 1.2 atm
Calculate the fraction of space that is occupied by packing spheres in the (a) simple cubic, (b) body-centered cubic, (c) face-centered cubic (close packed) structures
The phase diagram starts at 0K and gradually increases from 100k to 200k and as it hits 200K, the line splits apart increasing in pressure
The other criterion is very basic and relates to whether simple or fractional is selected
The composition of a gas on a dry basis is 77.0 mole % N2, 9.0% O2, 11.0% CO2, and 3.0% CO. If the mole fraction of water is 0.170, what is the gas composition on a wet basis

In a sample containing small grains of sand, what would you observe in the Mel-Temp apparatus when you melt the sample that would indicate to you that your sample contained this type of impurity
Question- If you were to return your 97-106 C fraction to the empty boiling flask and redistill it, you might expect it all to distill between 97-106C as it did the first time. It actually yields some distillate in all four boiling ranges. Explain..
