Mercury thermometers are being phased out because mercury is highly toxic. If a thermometer breaks, the mercury can evaporate and be inhaled, leading to severe health risks, including neurological damage. Additionally, mercury can contaminate the environment, posing long-term ecological hazards. As safer alternatives like digital and alcohol-based thermometers have become widely available, the use of mercury thermometers is declining, especially in medical and educational settings.

Digital thermometers are devices that use electronic sensors to detect temperature changes and provide a reading on a digital display. They are known for their speed and accuracy, making them popular in medical, industrial, and household contexts. Unlike traditional liquid-in-glass thermometers, digital thermometers can measure temperature in seconds and are available in various types, including oral, ear, and infrared models. They are user-friendly and often feature memory functions for tracking temperature changes over time.

An infrared thermometer is a device that measures temperature by detecting the infrared radiation emitted by an object. Since it doesn’t require physical contact, it’s ideal for measuring temperatures in situations where conventional thermometers are impractical, such as in industrial settings or when checking a person’s temperature without touching them. Infrared thermometers are fast, provide instant readings, and are often used for safety checks, food inspections, and medical diagnostics.

The resonance time of a Dead Hall is [A] zero seconds. A Dead Hall, also known as an anechoic chamber, is constructed with highly absorptive materials on all surfaces to eliminate any sound reflections. This intentional design ensures that sound waves are immediately absorbed upon impact with the surfaces, preventing them from bouncing back and causing reverberation.
Dead Halls are crucial for conducting precise acoustic measurements, testing equipment, and conducting research where minimal acoustic interference is essential. They are used in industries such as aerospace, automotive, and telecommunications to simulate free-field conditions without environmental noise or reverberation.
The concept of a Dead Hall contrasts with conventional halls and auditoriums, which are designed to enhance sound reflection and create desirable reverberation effects for music performance and speech intelligibility. In a Dead Hall, the absence of reverberation ensures accurate acoustic measurements and controlled experimental conditions.
