If ambient temperature is 300 K , the rate of cooling at 600 K ts H . In the same surroundings, the rate of cooling at 900 K is
Options
- A16 3 H
- B2H
- C3H
- D2 3 H
Correct answer
A. 16 3 H
Step-by-step solution
T ₀=300 ~K , ~T ₁=600 ~K , ~T ₂=900 ~K By stefan - Boltzmann law, Rate of cooling, Q ( T ^4- T ₀ ^4 ) aligned & Q ₂ Q = T ₂^4- T ₀^4 ~T ₁^4- T ₀^4 = (900)^4-(300)^4 (600)^4-(300)^4 & Q ₂ H = 81-1 16-1 = 80 15 & Q ₂= 16 3 H aligned
