Science

A lead calorimeter with mass of 150g contains 200g of water. The calorimeter and water are in thermal equilibrium at a specific temperature. Two metallic blocks are placed into the water. One is a 50.0g piece of aluminum heated at 90 degrees celcius. The other has a mass of 65g and is originally at a temperature of 97 degrees celcius. The entire system reaches a final temperature of 25 degrees celcius. (a) Find the final temp of the calorimeter and water. (b) Determine the specific heat of the sample.
