What is a "Glass thermometer" typically composed of?

A covering for the hand having separate sections for each of the fingers and the thumb
A glass bulb attached to a fine tube of glass with a numbered scale
The use of motions of the limbs or body as a means of expression
Convulsions resulting in loss of consciousness

The correct answer is: A glass bulb attached to a fine tube of glass with a numbered scale

The correct choice describes a glass thermometer accurately. A glass thermometer consists of a small glass bulb that contains a liquid, usually mercury or alcohol, which expands and rises up a narrow tube as the temperature increases. The numbered scale on the glass tube allows for precise measurement of temperature based on the level of the liquid. This design enables accurate readings, making it a traditional tool for temperature measurement in medical and scientific settings. The other options refer to unrelated concepts; one describes a type of glove, another relates to body language, and the last option refers to a medical condition. None of these pertain to the function or composition of a glass thermometer.
