Question
Qualitative Predictions about Entropy - Copy 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. 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 phenomenon. Part A For the following samples given below, consider the quantity of molecules (moles), the size of the molecule, the temperature of the sample, the occupied space (volume), and the state (gas or liq) when deciding which samples have a greater or lesser degreee of entrropy. Rank these systems in order of decreasing entropy. Rank from highest to lowest entropy. To rank items as equivalent, overlap them. ▸ View Available Hint(s) 1/2 mol of helium gas at 100 K and 20 L Greatest entropy 1 mol of hydrogen gas at 273 K and 40 L The correct ranking cannot be determined. 1/2 mol of helium gas at 273 K and 20 L 1 mol of helium gas at 273 K and 20 L 1 mol of helium gas at 273 K and 40 L 1/2 mol of liquid helium at 100 K 6 of 41 > Reset Help Review | Constants Periodic Table 1 mol of methane gas at 273 K and 40 L Least entropy
