The temperature of a substance increases by `27^(@)C`. On the Kelvin scale this increase is equal to

Options

A. `300 K`
B. `2.46 K`
C. `27 K`
D. `7 K`

Explanation

To solve the problem of converting the temperature increase from Celsius to Kelvin, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship Between Celsius and Kelvin:**
The Kelvin scale is related to the Celsius scale by the equation:
\[ T(K) = T(°C) + 273.15 \]
However, when considering changes in temperature, the constant (273.15) does not affect the difference.

2. **Identify the Change in Temperature:**
The problem states that the temperature of a substance increases by \(27°C\). This is the change in temperature we need to convert.

3. **Apply the Change in Temperature:**
Since the change in temperature in Celsius is equal to the change in temperature in Kelvin, we can directly state:
\[ \Delta T(K) = \Delta T(°C) \]
Therefore:
\[ \Delta T(K) = 27°C \]

4. **Conclude the Result:**
The increase in temperature on the Kelvin scale is:
\[ \Delta T(K) = 27 K \]

### Final Answer:
The increase in temperature on the Kelvin scale is \(27 K\).
