7. Kepler-186f is an exoplanet that orbits a star other than the Sun. Its star is the red dwarf Kepler-186. It is the first planet to be discovered that orbits its star at a distance similar to Earth's distance from the Sun.
If Kepler-186f is approximately 5.4 x 10^10meters from Kepler-186, how long does it take for light from
the star to reach the exoplanet? The speed of light is 3.0 x 10^8 m/s.

there all right good

explanation:

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
