telo118 [61]

Answer:

-173.15°C

Explanation:

Given data:

Temperature changes = 100 K

Temperature changes in degree Celsius = ?

Solution:

Kelvin and degree Celsius both are units of temperature.

In order to convert the degree Celsius to kelvin following equation is used.

Temperature in degree Celsius +273.15

For example;

100°C to kelvin = 100+273.15 = 373.15 K

To convert the kelvin into degree Celsius:

100K - 272.15 = -173.15°C
