Question

Convert the following temperatures to the Kelvin scale.

1. $28°C$
2. $18°C$
3. $38°C$

Answer 1

Step-1:

Formulae:

The temperature on the Kelvin scale = Temperature on the Celsius scale $+273$

Step-2:

1. The temperature on the Celsius scale $=28°C$

The temperature on the Kelvin scale$=28+273=301K$

Thus, a temperature $28°C$ on the Celsius scale is equal to $301K$ on the Kelvin scale.

Step-3:

2. the temperature on the Celsius scale $=18°C$

The temperature on the Kelvin scale$=18+273=291K$

Thus, a temperature $18°C$ on the Celsius scale is equal to $291K$ on the Kelvin scale.

Step-4:

3. the temperature on the Celsius scale $=38°C$

The temperature on the Kelvin scale$=38+273=311K$

Thus, a temperature $38°C$ on the Celsius scale is equal to $311K$ on the Kelvin scale.
