Entropy is a measure of
heat energy
temperature
the disorder/randomness of a system
A small S value indicates the system has _______
more order
more randomness
Which process is accompanied by a decrease in entropy?
boiling of water
condensing of water vapor
subliming of iodine
melting of ice
Given the change of phase:
CO2(g) —> CO2(s)
As CO2(g) changes to CO2(s), the entropy of the system
decreases
increases
remains the same
Identify whether the following result in an increase or decrease in entropy:
3 moles of gas (on reactant side) --> 6 moles of gas (product)
increase
decrease
The entropy will usually increase when
a molecule is broken into two or more smaller molecules
a reaction occurs that results in an increase in the number of moles of gas
a solid changes to a liquid
all of these
