What is the absolute temperature of +20 degrees Celsius in Kelvin?

To convert a temperature from degrees Celsius to Kelvin, the formula used is:

[ K = C + 273.15 ]

Where ( K ) represents the temperature in Kelvin and ( C ) is the temperature in degrees Celsius.

When given +20 degrees Celsius, you can substitute into the formula:

[ K = 20 + 273.15 = 293.15 ]

For practical purposes, we often round this to 293 K. Therefore, the correct conversion of +20 degrees Celsius results in an absolute temperature of 293 Kelvin.

This understanding is fundamental because Kelvin is a key unit of temperature in scientific contexts, particularly in fields like HVAC where absolute temperature measurements are essential for calculations involving thermodynamic processes and principles. Knowing how to accurately convert between these temperature scales ensures effective communication and computation in technical practice.
