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.
Liquid-in-glass thermometers work by using the expansion and contraction of a liquid, like mercury or alcohol, inside a glass tube. The liquid’s level rises or falls as temperature changes.
Absolute zero is the lowest possible temperature, 0 Kelvin or -273.15°C, where molecular motion theoretically ceases entirely. It is a fundamental concept in thermodynamics.
The Kelvin scale is an absolute temperature scale starting at absolute zero (0 K). It is commonly used in scientific research and calculations.
No, a cricket ball cannot be used to play tennis because it is too hard, heavy and lacks the required bounce. Tennis balls are lighter, softer and specifically designed to suit the game’s dynamics.
Different materials are used for making sports balls to suit the specific needs of each game, such as durability, bounce, weight, and grip. These factors influence the ball’s performance and player control in different environments.
