A 5.00 gram sample of an unknown metal was placed in a beaker of boiling water (99.58 oC). After five minutes it was immediately transferred from the boiling water to a calorimeter containing 50.0 mL of water at 11.25 oC. The final temperature of the metal-water mixture was 44.10 oC. What is the specific heat of the metal

In a heat engine of 1000 j of heat enters the system and the piston does 500 j of work what is the final internal energy of the system if the inital energy was 2000 j we have to do all of these down here 1)write the equation 2)list out your know variables 3)plug the numbers into the equations 4)solve 5)write your solution statemtn that includes inital energuy and final energuy added
