Determine what was the final temperature of the coins

Reference no: EM13556454

In a physics lab experiment, a student immersed 207 one-cent coins (each having a mass of 3.00 g ) in boiling water. After they reached thermal equilibrium, she quickly fished them out and dropped them into 0.241 kg of water at 20.0 degrees C in an insulated container of negligible mass.

A) What was the final temperature of the coins? [One-cent coins are made of a metal alloy - mostly zinc - with a specific heat capacity of 390 J/(kg* K).]

Tf = _____ degrees C
