If the rates of cooling of two different liquids put in exactly similar calorimeters and kept in identical surroundings are the same, then which among the following is most suitable option?

Step-by-step solution

d θ dt = σ A mc T 4 - T 0 4 . If the liquids put in exactly similar calorimeters and identical surrounding then we can consider T 0 and A constant then d θ dt ∝ T 4 - T 0 4 mc If we consider that equal masses of liquid (m) are taken at the same temperature then d θ dt ∝ 1 c So for same rate of cooling c should be equal which is not possible because liquids are of different nature. Again from equation (i) d θ dt ∝ T 4 - T 0 4 mc ⇒ d θ dt ∝ T 4 - T 0 4 V ρ c Now if we consider that equal volume of liquid (V) are take
