You cool a 120.0 g slug of red-hot iron (temperature 745 ∘C) by dropping it into an insulated cup of negligible mass containing 75.0 g of water at 20.0 ∘C. Assume no heat exchange with the surroundings.
A. What is the final temperature of the water?
B. What is the final mass of the iron and the remaining water?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

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.)
