Question

A 10.0 gram piece of metal is placed in an insulated calorimeter containing 250.0 grams of water initially at 20.0°c. if the final temperature of the mixture is 25.0°c, what is the heat change of piece of metal? 5230 j â5230 j 209 j â209 j 5440 j

Answer 1

-5230 J Given the above data, the piece of metal raised the temperature of 250.0 grams of water from 20.0°C to 25.0°C. So there was a change of 5.0°C The specific heat of water is 4.184 joules per gram which is the amount of energy needed to rais
