Consider the following statements.
(A) A hot body is kept in some surrounding. As it cools, its temperature falls from 80°C to 78°C in a time duration t₁ and from 50°C to 48°C in time duration t₂. The temperature of surrounding is constantly 20°C, then t₁ > t₂.
(B) According to Newton's law of cooling; rate of cooling depends only on the difference of temperatures of the body and the surrounding.

Select the correct option.
(a) (A) is false but (B) is true.
(b) Both (A) and (B) are true.
(c) (A) is true but (B) is false.
(d) Both (A) and (B) are false.
 

• A

  Both (A) and (B) are true.

• B

  (A) is true but (B) is false.

• C
