In terms of disorder and energy, systems in nature have a tendency to undergo changes toward

less disorder and lower

energy

less disorder and higher energy

greater disorder and lower energy

greater disorder and higher energy

Option C is correct

Explanation:

Entropy is defined as the randomness in a system. In nature, a system tends to have high entropy. The higher the entropy , the spontaneous the reactions would be. As a system loses energy, it becomes more ordered and less random. Hence, as the reaction proceeds in a system, the system  has higher energy/entropy and less order.  

Hence, option c is correct

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
