Q.1
Entropy of a system decreases when mixing occurs.
  • True
  • False
Q.2
Entropy of a system increases when it undergoes a change of state.
  • True
  • False
Q.3
Entropy of a system increases when it gains energy.
  • True

Q.4
For a chemical reaction to be feasible, the total entropy change must be zero. (∆Ssystem + ∆Ssurroundings = 0)
  • True
  • False
Q.5
The more widely spread out energy is among available energy levels and particles, the less probable that state.
  • True

Q.6
Entropy is a measure of the number of ways in which energy is distributed.
  • True
  • False
Q.7
Entropy is a form of energy
  • True
