Two large containers A and B of the same size are filled withdifferent fluids. The fluids in containers A and B are maintainedat 0° C and 100° C, respectively. A small metal bar, whose initialtemperature is 100° C, is lowered into container A. After 1 minutethe temperature of the bar is 90° C. After 2 minutes the bar isremoved and instantly transferred to the other container. After 1minute in container B, the temperature of the bar rises 10o. Howlong, measured from the start of the entire process, will it takethe bar to reach 99.5° C?
A small metal bar, whose initial temperature was 30° C, isdropped into a large container of boiling water. How long will ittake the bar to reach 80° C if it is known that its temperatureincreases 2° during the first second? (The boiling temperature forwater is 100° C. Round your answer to one decimal place.) sec Howlong will it take the bar to reach 95° C? (Round your answer to onedecimal place.) sec
