How do you measure maximum temperature?
Maximum and minimum temperatures are measured using thermometers mounted inside a wooden box with slits, called Stevenson’s screen, which is generally kept facing north. The maximum thermometer is mercury-in-glass — as the temperature rises, the mercury expands and moves freely up a constriction in the thermometer.
What is range of normal body temp?
98.6°F
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
How does a maximum and minimum thermometer measure temperature?
The maximum temperature is read at the level of the bottom of the maximum marker, the minimum temperature is read at the bottom of the minimum marker. 3. Record the present temperature by reading at the top of the mercury column on either side (they read the same on the maximum or the minimum side).
How does a max min thermometer work and how does it work?
A maximum-minimum thermometer works by registering the maximum and minimum temperatures over a certain time period by using two scales set in liquid mercury. Two bulbs filled with alcohol or oil regulate the movement of the mercury. Maximum-minimum thermometers are typically U-shaped parallel tubes of glass. Click to see full answer.
How does a thermometer record minimum and maximum temperature?
The top half of the tube that records the minimum temperature contains alcohol; the top half of the tube that records the maximum temperature contains a vacuum or low-pressure alcohol vapour. As the alcohol expands in response to temperature changes, floats on both sides of the thermometer record the minimum and maximum temperatures.
How is mercury used as a thermometer liquid?
Mercury is used as thermometric liquid. There is a steel index inserted inside the capillary tube. Spring connected to the index prevents it from moving back to the bulb. With increasing temperature, mercury expands and pushes the steel index along the capillary tube. The index will be left at the furthest position to which mercury has expanded.
What’s the best way to reset a thermometer?
Push Button – The MIN/MAX thermometer is reset by using the push button normally found in the middle of the thermometer between the two tubes. 1. After you have taken the minimum and maximum readings, simply hold in the push-button to reset the magnetic indicators for the next day’s data.
