Question

The fundamental interval of which two temperature scale is the same

Answer 1

The upper and lower points of Reaumur  scale are 80°R and 0°R and fundamental interval is 80°. The upper and lower points of Kelvin scale are 373 K and 273 K and the fundamental interval is 100°.

Answer 2

Kelvin scale and Celsius scale have the same fundamental interval of temperature.

Kelvin scale is a scale of temperature whose absolute zero is zero kelvin, and water has its triple point at 273.16 degrees.

The Celsius scale is also known as the centigrade scale. It is a temperature scale that is used by the International System of Units.

Relationship between celsius and kelvin scale is:

0°C = 273 K
