On centrigrade scale the temperature of body increases by 45 degree. The increase in temperature on kelvin scale is

Options

A. 318K
B. 45K
C. 245K
D. 363K

Answer

To solve the problem of finding the increase in temperature on the Kelvin scale when the temperature increases by 45 degrees Celsius, 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, for temperature differences, we can use the simpler relationship:
\[ \Delta T(K) = \Delta T(°C) \]
This means that a change in temperature in degrees Celsius is equal to the change in temperature in Kelvin.

2. **Identify the increase in temperature**:
According to the problem, the temperature of the body increases by 45 degrees Celsius. Thus:
\[ \Delta T(°C) = 45 \]

3. **Calculate the increase in temperature in Kelvin**:
Since the increase in temperature in Kelvin is the same as the increase in temperature in Celsius:
\[ \Delta T(K) = \Delta T(°C) = 45 \]

4. **Conclusion**:
The increase in temperature on the Kelvin scale is therefore:
\[ \Delta T(K) = 45 \text{ K} \]

### Final Answer:
The increase in temperature on the Kelvin scale is **45 K**.
