1. Calculate the one temperature at which Fahrenheit and Kelvin thermometers agree with each other. 2. An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10°C. Two metallic blocks are placed into the water. One is a 50g piece of copper at 80°C. The other block has a mass of 70.0 g and is originally at a temperature of 100°C. The entire system stabilizes at a fixed temperature of 20°C. Determine the specific heat of the unknown material. Given: CAL = 0.910 g·c° Ccopper = 0.390 %3D C° Cwater = 4. 186 '/g · c°º
