A small metal bar, whose initial temperature was 10° C, is dropped into a large container of boiling water. How long will it take the bar to reach 80° C if it is known that its temperature increases 2° during the first second? (The boiling temperature for water is 100° C. Round your answer to one decimal place.) 90 x sec How long will it take the bar to reach 99° C? (Round your answer to one decimal place.) 200.2 sec
