Convert 25 Degree Celsius into Kelvin Scale

To convert a temperature from Celsius (°C) to Kelvin (K), we use the following formula:

K=°C+273.15K = °C + 273.15

This formula works because the Kelvin scale starts at absolute zero, which is 273.15273.15 degrees below zero on the Celsius scale. The Kelvin scale does not use negative numbers, making it especially useful in scientific measurements.

Step-by-Step Conversion of 25°C to Kelvin:

1. Write down the given temperature in Celsius:

   25°C

2. Use the formula to convert Celsius to Kelvin:

   K=°C+273.15K = °C + 273.15

3. Substitute 25°C into the formula:

   K=25+273.15K = 25 + 273.15

4. Perform the addition:

   K=298.15K = 298.15

Thus, the temperature 25°C is equal to 298.15 K.

Understanding the Kelvin Scale:

• Celsius and Kelvin scales differ only by a shift of 273.15273.15, meaning they have the same size degree increment.
• The Kelvin scale starts at absolute zero, the theoretical point where molecular motion ceases, corresponding to 0 K or −273.15°C.
• Kelvin is widely used in science for measuring temperature because it provides an absolute reference point.

Example Contexts:

• Room temperature (25∘C) is often approximately 298.15 K.
• This conversion is essential in physics, chemistry, and other sciences, where temperature calculations use Kelvin due to its direct relationship with energy and thermodynamic equations.
