Endless movement between hot and cold will eventually mean the end of the universe. This law is about inefficiency, degeneration and decay. <u>The second law can be expressed in several ways, the simplest being that heat will naturally flow from a hotter to a colder body. At its heart is a property of thermodynamic systems called entropy.</u> Entropy basically means an increase in randomness. Hope this helps mate.
Explanation:
Correct. Air has an index of refraction of approximately 1, and the angle of incidence is 35°. The substance has an unknown index of refraction n, and the angle of refraction is 25°.
1 sin 35° = n sin 25°
n = 1.36
