Why is it necessary to have a standard thermometer?
Worked Solution & Example Answer:Why is it necessary to have a standard thermometer? - Leaving Cert Physics - Question c - 2009
Step 1
Different thermometers have different thermometric properties
Answer
Different types of thermometers utilize various methods for measuring temperature, such as mercury, digital, or infrared technologies. Each type may respond differently to temperature changes, leading to inconsistencies in readings. A standard thermometer ensures uniformity in temperature measurement by adhering to specific properties, allowing for reliable comparisons across different devices.
Step 2
Give different readings (at the same temperature)
Answer
At the same temperature, different thermometers can yield varying readings due to calibration differences, material properties, or design. This discrepancy can result in significant implications, particularly in scientific experiments or industrial applications. The use of a standard thermometer provides a baseline, facilitating accurate and consistent temperature readings across different instruments.
