Explanation
The Kelvin scale is the SI unit used for measuring temperature in scientific work, starting at absolute zero, the theoretical point at which particle motion is at a minimum, with no negative values on the scale. While Celsius is commonly used in everyday life in most countries, Kelvin is preferred in science because it directly relates temperature to the actual thermal energy of a substance. A temperature change of one degree on the Kelvin scale is equal in size to a change of one degree Celsius. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
