Answer:

The thermometer can not be used to measure very low temperature

Explanation:

Mercury-in-glass thermometer is one of the types of liquid-in-glass thermometers.

Given the very melting point of mercury, it is unsuitable to attempt to use this thermometer for very low temperature measurement.

Hence, from the melting point of mercury, this thermometer can not be used to measure very low temperature.
