If the temperature of a hot body is increased by 50 % , then the increase in the quantity of emitted heat radiation will be approximately

Step-by-step solution

aligned & Given: T ₂= T ₁+ 50 100 ~T ₁ & ~T ₂=1.5 ~T ₁ aligned According to Stefan's law, Q At = T ^4 Percentage change in radiation is, aligned & E %= T ₂^4- T ₁^4 ~T ₁^4 100 & E %= (1.5)^4 ~T ₁^4- T ₁^4 ~T ₁^4 100 & E % 400 % aligned
