0.2000 kg of water at 20.00°c is contained in a 0.1000-kg copper container. the container is shaken vigorously for 10.00 minutes to cause the temperature to rise to 22.00°c. calculate the work done on the system and the heat supplied to the system. the specific heat of copper is 385.0 j/kg and of water is 4200.0 j/kg

Asmall 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 70° 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.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)
