Animal body temperatures are measured using digital or mercury thermometers, typically rectally for accuracy. Each species has its own normal range: cats and dogs around 101-102°F, horses 99-101°F, camels 97-101°F, cows and buffaloes 100.5-102.5°F.
If someone says she has a fever of 101 degrees, she is most likely referring to the Fahrenheit scale. A temperature of 101°F is a common fever range, while 101°C would be dangerously high.
Each division of a laboratory thermometer with 50 divisions between 0°C and 100°C measures 2°C. This is calculated by dividing the total temperature range (100°C – 0°C) by the number of divisions.
A laboratory thermometer is not used to measure body temperature because it has a wide range and low sensitivity, which makes it unsuitable for accurately measuring the narrow temperature range of the human body.
Infrared thermometers work by detecting infrared radiation emitted by an object. They use sensors to convert this radiation into an electrical signal, which is then displayed as a temperature reading.
An infrared thermometer measures temperature by detecting infrared radiation emitted by objects. It allows non-contact temperature measurement, making it useful for both industrial and medical purposes.
Digital thermometers use electronic sensors to measure temperature and display the reading on a digital screen. They are fast, accurate, and commonly used in medical, industrial, and household applications.
The Kelvin scale is important in science because it starts at absolute zero, providing a direct measure of thermal energy. It is used in scientific calculations and studies involving temperature.
Mercury thermometers are being phased out due to the toxicity of mercury. If broken, mercury can pose serious health and environmental risks.
