🔍 Key Concepts

• Behavior of mercury inside a glass thermometer when shaken or swung • Effect of holding the thermometer by the upper vs. lower end on the mercury column • Practical limits of repairing vs. replacing a damaged thermometer

💭 Think About

• Think about what motion will move the separated mercury droplets toward each other inside the tube. • Consider whether tapping lightly on glass is effective for moving liquid metal in a narrow capillary, or if a stronger centrifugal-like motion is needed. • Ask yourself: if you want all the mercury to move down into one column, which end of the thermometer would you hold so the mercury moves in the correct direction?

✅ Before You Answer

• Visualize the direction the mercury must travel to recombine into a single column. • Check whether the chosen method could break or damage the glass thermometer, making it unsafe or unusable. • Confirm whether the method described would realistically allow the mercury segments to slide and join rather than stay separated.

If the mercury has become separated in a liquid-in-glass thermometer, what can be done to correct this situation?

After removing the thermometer, hold the thermometer by the upper end and try to recombine the mercury by several full arm swings.

Repeatedly tap the side of the thermometer until the mercury recombines.

After removing the thermometer, hold the thermometer by the lower end and try to recombine the mercury by several full arm swings.

It is not possible to correct this situation.
