A hot body, initially at a temperature 8θ , is present in surroundings that are at a temperature θ . The time intervals, for its temperature to fall from, (i) 8θ to 4θ and (ii) 4θ to 2θ , are Δt1 and Δt2 , respectively. The ratio (Δt1/Δt2) equals
(1) 2
(2) log 2
(3) \(\frac{log^{7/3}}{log(3)}\)
(4) \(\left[\frac{log7}{log2}\right]\)
