A
Spherical bulb thermometer
💡 Explanation:
A spherical bulb has a smaller surface-area-to-volume ratio than a cylindrical bulb of similar volume, but a cylindrical bulb is often designed to have a larger surface area for faster heat exchange. However, the spherical shape is generally more robust, while the cylindrical shape responds faster due to higher surface area exposure.
