Question

Name two submultiples of the unit kilogram.
3. Name an instrument generally used to find the time interval between two events accurately.
What are the two fixed points in the Celsius scale?
5. What is the symbol of the unit kelvin? [K]​

Answer 1

Answer:

Two sub multiples of kg are gram and milligram

A stopwatch is a handheld timepiece designed to measure the amount of time that elapses between its activation and deactivation

In the Celsius scale, the freezing point of water is 0 oC and the boiling point is 100 oC, so that there are 100 Co between the two fixed points. (When Celsius originally introduced his scale, he set the temperature of boiling water as 0, and the temperature of melting ice as 100

The 13th CGPM (1967) adopted the name kelvin (symbol K) instead of "degree Kelvin" (symbol °K) and defined the unit of thermodynamic temperature as follows: The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.

Answer 2

Answer:

Two sub multiples of kg are gram and milligram

3.A stopwatch is a handheld timepiece designed to measure the amount of time that elapses between its activation and deactivation.

5.The 13th CGPM (1967) adopted the name kelvin (symbol K) instead of "degree Kelvin" (symbol °K) and defined the unit of thermodynamic temperature as follows: The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
