In a laboratory setting, how might thermal expansion affect the precision of a volumetric flask measurement?

• A. Thermal expansion causes the flask to deliver a smaller volume than intended, increasing precision.
• B. Thermal expansion can cause the flask to deliver a larger volume than intended, reducing precision.
• C. Thermal expansion only affects the color of the solution, not the volume.
• D. Thermal expansion has no effect on the precision of volumetric measurements.

Answer: (B)
