Is her calculation correct? Choose the best answer and explanation from the following:
A. No, because volume is a positive number.
B. Yes, because the negative sign means the volume decreased.
C.No, because the volume actually increased.
D.No, because temperature must ALWAYS be in degrees Kelvin for the calculation to
be correct.
Question 3
