Express `20^(@)C` in kelvin scale.

Answer

To convert 20 degrees Celsius (°C) into Kelvin (K), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Conversion Formula**:
The formula to convert Celsius to Kelvin is:
\[ K = °C + 273.15 \]

2. **Identify the Given Temperature**:
In this case, the temperature given is:
\[ °C = 20 \]

3. **Substitute the Value into the Formula**:
Now, we substitute the value of °C into the conversion formula:
\[ K = 20 + 273.15 \]

4. **Perform the Calculation**:
Now, we add the two values:
\[ K = 293.15 \]

5. **State the Final Answer**:
Therefore, the temperature of 20 degrees Celsius is equivalent to:
\[ 20°C = 293.15 K \]

### Final Answer:
20 degrees Celsius is equal to 293.15 Kelvin.
