Which of the following would be SI unit to use in measuring the temperature of hot liquid

The unit is the Kelvin, but most of the time 273 is subtracted from the Kelvin temperature and the new number is called "degrees Celsius".

Answer: Kelvin (K)

Explanation:

As we know that there are seven fundamental SI units which are used to fine derived units. These are as follows:

1). Mass - Kilogram

2). Length - meter

3). Time - Seconds

4). Electric Current - Ampere

5). Amount of substance - Moles

6). Temperature - Kelvin

7). Intensity of light - Candela

Thus Kelvin would be the S. I. unit to use in measuring the temperature of hot liquid.
