Conversion of Temperature to the Kelvin Scale

To convert a temperature from Celsius or Fahrenheit to the Kelvin scale, we need to understand the concept of absolute zero and the relationship between the Kelvin and Celsius scales.

Absolute Zero:
Absolute zero is the lowest possible temperature, at which the particles of matter have the minimum amount of thermal energy. It is defined as 0 Kelvin (0 K) or -273.15 degrees Celsius (-273.15 °C). At absolute zero, all molecular motion ceases.

Relationship between Kelvin and Celsius Scales:
The Kelvin scale is an absolute temperature scale, whereas the Celsius scale is a relative temperature scale. The Kelvin scale starts from absolute zero, while the Celsius scale starts from the freezing point of water (0 °C).

The relationship between the Kelvin (K) and Celsius (°C) scales can be represented by the equation:
K = °C + 273.15

Conversion Process:
To convert a temperature from Celsius or Fahrenheit to the Kelvin scale, follow these steps:

1. Determine the given temperature in Celsius or Fahrenheit.
2. If the temperature is given in Celsius, proceed to step 3. If the temperature is given in Fahrenheit, convert it to Celsius using the formula: °C = (°F - 32) × 5/9.
3. Add 273.15 to the temperature in Celsius to obtain the temperature in Kelvin.

Example:
Let's convert a temperature of 25 °C to the Kelvin scale.

Given: Temperature = 25 °C

Step 1: The given temperature is in Celsius.

Step 2: No conversion needed.

Step 3: Add 273.15 to 25 °C:
Temperature in Kelvin (K) = 25 °C + 273.15 = 298.15 K

Therefore, a temperature of 25 °C is equivalent to 298.15 K on the Kelvin scale.

Summary:
Converting a temperature to the Kelvin scale involves adding 273.15 to the temperature in Celsius. The Kelvin scale starts from absolute zero, which is the lowest possible temperature. Understanding the relationship between the Kelvin and Celsius scales allows us to easily convert temperatures between the two scales.
