My first answer was wrong. Can you explain answers?
Entropy is the randomness of a system. At the molecular level, entropy can be described in terms of the possible number of different arrangements of particle positions and energies, called microstates. The more microstates the system has, the greater its entropy Microstates depend on molecular motion. Molecules may undergo three different types of motion: translational motion, vibrational motion, and rotational motion. During translational motion, the entire molecule moves in one direction. During vibrational motion, atoms in a molecule move toward and away from one another. Duing rotational motion, molecules rotate or spin. The number of molecules, the space available for the molecules, and the energy available to the molecules will impact the number of microstates. Another way of looking at entropy is that the universe is moving toward a broader distribution of energy. The universe has a constant amount of energy as stated in the first law of thermodynamics. The universe started with low entropy (concentrated in the moment before the "big bang") and the entropy has since been constantly increasing by distributing this energy. Heat distribution from high temperature to low temperature is a another example of this phenomenorn Part A Rank these systems in order of decreasing entropy. Rank from highest to lowest entropy. To rank items as equivalent, overlap them. Hints Reset Help Greatest entropy Least entropy 1 mol of 1/2 mol of radon gas at 273 K and 20 L 1 mol of radon gas at 273 K and 20 L 1/2 mol of radon gas at 100 K and 20 L 1/2 mol of liquid radon at 100 K 1 mol of 1 mol of radon gas at 273 K and 40 L nitrogen gas at 273 K and 40 L nitrogen dioxide gas at 273 K and 40 L
