Question
2) a 36.0 g peice of copper metaal is intially at 100 degreeC. it is dropped into a coffee cup calorimeter containing 50.0 g ofwater at a temperature of 20.0 degree C. after stirring,, the finaltemp of both copper and water is 25.0 degree C. Assuming no heatlooses, what is the specific heat capacity of copper? (Specificheat capacitu of water is 4.18 J/g.K) 2) a 36.0 g peice of copper metaal is intially at 100 degreeC. it is dropped into a coffee cup calorimeter containing 50.0 g ofwater at a temperature of 20.0 degree C. after stirring,, the finaltemp of both copper and water is 25.0 degree C. Assuming no heatlooses, what is the specific heat capacity of copper? (Specificheat capacitu of water is 4.18 J/g.K)Explanation / Answer
Heat lost by copper = Heat gained by watermc dt = MCdt' 36 * c * ( 100 - 25 ) = 50 * 4.18 * (25-20) c = 0.387 J / g-K
