The following statements are mainly about energy, with a few about the related concept of entropy. Which do you think are true and which do you think are false?
A Every change that happens involves an energy change.
B The First Law of Thermodynamics says that energy is neither created nor destroyed.
C Energy is the cause of change.
D Energy doesn’t really exist, as it is just a value that can be calculated.
E The Second Law of Thermodynamics essentially says that at the molecular level things tend to get jumbled up or disordered.
F The Second Law of Thermodynamics does not apply to living things, but it does when they die and decay.
G In a spontaneous process entropy always increases.
H Entropy is a measure of how ordered a system is at the molecular level – the more ordered, the higher the entropy.
I When we exercise our bodies we use up energy.
J When we exercise our bodies we make energy.
