Which of the following processes would you predict to have an increase in entropy?

condensation of water

freezing water

melting ice

deposition of co2 (changing from a gas to solid)

melting ice

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

1. condensation of water : Condensation process is a process where gaseous state changes to liquid state., thus decreasing randomness and decreasing entropy.

2. Freezing water : Freezing process is a process where liquid state changes to solid state, thus decreasing randomness and decreasing entropy.

3. melting ice: Fusion process is a process where solid state changes to liquid state, thus increasing randomness and increasing entropy.

4. deposition of : deposition process where gaseous state changes to solid state by escaping liquid state, thus decreasing randomness and decreasing entropy.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
