A student has the following data: V1 = 822 mL; T1 = 75.0 °C; T2 = 25.0 °C. She uses this data to calculate V1 and gets -274 mL.
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
You calculate the volume yourself to verify that her calculations are correct. What should the correct volume be?

A.-274 mL
B.274 mL
C.82.2 mL
D.-82.2 mL
