An ideal gas is compressed isobarically to one-third of its initial volume. The resulting pressure will be
A) three times as large as the initial value.
B) nine times the initial value.
C) more than three times as large as the initial value.
D) equal to the initial value.
E) impossible to predict on the basis of this data.

Question
