A cane is taken out from a refrigerator at $ 0{}^\circ C $ . The atmospheric temperature is $ 25{}^\circ C $ . If $ {{t}_{1}} $ is the time taken to heat from $ 0{}^\circ C $ to $ 5{}^\circ C $ and $ {{t}_{2}} $ is the time taken from $ 10{}^\circ C $ to $ 15{}^\circ C $ , then

• A. $ {{t}_{1}}>{{t}_{2}} $
• B. $ {{t}_{1}}<{{t}_{2}} $
• C. $ {{t}_{1}}={{t}_{2}} $
• D. there is no relation

Answer 1

Answer: (B)

According to Newtons law of cooling $ {{t}_{1}} $ will be less than $ {{t}_{2}} $ .
