Camels feel relief from the desert heat by increasing their body temperature to 42°C. This allows them to conserve water by reducing sweating and water loss. Camels also have adaptations like fat storage in humps, long legs, and thick fur ...

By increasing the pressure on ice, its melting point will increase. Pressure affects the equilibrium between solid and liquid phases. As pressure rises, the equilibrium shifts towards the more compact solid phase, requiring a higher temperature to maintain equilibrium, resulting ...
Gas thermometers are more sensitive than liquid thermometers because gases has higher coefficient of expansion. Gas molecules expand more readily in response to temperature changes compared to liquids, leading to more significant changes in volume for a given temperature change. ...
Thermo Couple Thermometer is based on Seebeck’s effect. This principle states that when two dissimilar metals are joined at two junctions and one junction is at a different temperature, an electromotive force (EMF) is generated, creating a voltage that is ...
Very high temperatures are measured by Absolute radiation thermometer. Absolute radiation thermometers, also known as pyrometers, measure temperatures based on the intensity of thermal radiation emitted by an object. They are suitable for measuring extremely high temperatures, such as those ...
Total Radiation Pyrometer is based on Stephen’s law. This principle states that the total radiant flux emitted by a black body is proportional to the fourth power of its absolute temperature. Total Radiation Pyrometers utilize this law to measure temperature ...
Sun’s temperature is measured by pyrometer thermometer. Pyrometers, specifically designed for high temperatures, are used. They determine temperature by comparing the brightness or color of the Sun’s light to a calibrated filament’s brightness or color. This allows inference of the ...
In cold countries, alcohol is preferred over mercury as a thermometer liquid because the melting point of alcohol can be lower. This ensures that alcohol remains liquid at lower temperatures, making it effective for use in cold climates where mercury ...
Thermocouples are made by two dissimilar metals. When these metals are joined at both ends, a voltage is generated when there is a temperature difference between the junctions. This voltage can be measured and used to determine the temperature.
Radiation pyrometers measure temperatures above 800°C. These instruments detect thermal radiation emitted by an object and convert it into a temperature reading. They are commonly used in high-temperature industrial processes such as metalworking, ceramics, and glass manufacturing, where temperatures exceed ...
