Predict whether each of the following transformation leads to an increase or decrease in the entropy of a system. DO THE FOLLOWING DECREASE OR INCREASE IN ENTROPY
a- Br2(l) to Br2(g)
b- I2(g) to I2(s)
c- higher density S(a) to lower density S(B)
d- C (graphite) to C (diamonds)
e- NaCl(s) to NaCl(aq)

19. at high pressures, how does the volume of a real gas compare with the volume of an ideal gas under the same conditions, and why? eman- it is much less because real gas partides are not moving. there is no difference because the gas laws are always obeyed. it is much less because at high pressures the temperature drops. it is much greater because real gas partides take up space.

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.
