Assignment Help Physics
Reference no: EM131443513

A 50.0 g silver spoon at 20.0 oC is placed in a cup of coffee at 90.0 oC. The spoon heats while the coffee cools. The final temperature of the spoon and the coffee is 89.2 oC. The coffee cools while the spoon heats. Assuming the specific heat of coffee to be the same as the specific heat of water (4.19 J/g.oC) and knowing the specific heat of silver to be 0.235 J/g.oC, what is the mass of the coffee?
