Explain why it would not make sense to use a full-size glass thermometer to measure the temperature of a thimbleful of hot water.
The reason behind the fact that a full size of a glass thermometer can not be used to measure the temperature of a thimbleful of hot water.
Explanation of Solution
A glass thermometer has a bulb that carries mercury and this bulb is connected to a glass tube which has a very small diameter.
Heat in a thimbleful of water is small as compared to the heat that is required to heat the mercury.
In a glass thermometer mercury is used and the temperature that is attained from thimbleful of hot water is not sufficient to enlarge the mercury. Thus a glass thermometer cannot be used to ascertain the temperature of a thimbleful of hot water.
Conclusion:
The full size of a glass thermometer cannot be used to measure the temperature of a thimbleful of hot water.

When the thermometer was placed under your tongue, the warmed mercury would expand into a very narrow cylindrical channel, called a capillary, whose radius was 2.0 × 10-2 mm.
