Answer»

first case assuming vessels different if vessels are made up of different matters then we cant say anything that which one will cooled faster because radiation part will matter here

other case

assuming vessels same

as per Newtown law of cooling temperature difference will be directly proportional to time taken to cool

thus 60°c will take less time than 80°c vessel
