To find the total rate of radiation of energy from the thin square steel plate, we will use the Stefan-Boltzmann law. Here’s the step-by-step solution: ### Step 1: Convert the temperature from Celsius to Kelvin The temperature in Celsius is given as \(800^\circ C\). To convert this to Kelvin, we use the formula: \[ T(K) = T(°C) + 273 \] Substituting the given temperature: ...
