State how the clinical thermometer can be made quick acting?

The clinical thermometer can be made quick acting by using a thin glass tube with a small diameter, which allows for faster heat transfer between the body and the thermometer. Additionally, using a temperature-sensitive material with a high thermal conductivity, such as mercury or alcohol, can also help the thermometer respond quickly to changes in temperature. Finally, ensuring that the thermometer is properly calibrated and accurate can also help it provide quick and reliable temperature readings.

Methods to make a clinical thermometer quick acting:

- Use a thinner mercury column: Reducing the diameter of the mercury column decreases its thermal mass, allowing it to respond faster to temperature changes.

- Shorten the mercury column: A shorter column has less mass to heat up, resulting in quicker response times.

- Enclose the bulb in a thin glass envelope: This reduces the thermal insulation around the bulb, allowing it to conduct heat more efficiently.

- Reduce the size of the bulb: A smaller bulb has a smaller thermal mass and therefore responds faster to temperature changes.

- Tilt the thermometer at an angle when shaking it down: This distributes the mercury over a larger surface area, facilitating heat transfer and reducing the time it takes to reach the correct temperature.

- Use a digital thermometer: Digital thermometers utilize electronic sensors that can measure temperature changes very quickly, providing near-instantaneous readings.
