A body of emissivity `(e = 0.75)`, surface area of `300cm^(2)` and temperature `227^(@)C` is kept in a room at temperature `27^(@)C`. Calculate the initial value of net power emitted by the body.

Text Solution

AI Generated Solution

To calculate the initial value of net power emitted by the body, we will follow these steps: ### Step 1: Convert temperatures from Celsius to Kelvin - The temperature of the body \( T \) is given as \( 227^\circ C \). - To convert to Kelvin, we use the formula: \[ T(K) = T(°C) + 273 \] ...
