You are working in your kitchen preparing lunch for your family. You have decided to make egg salad sandwiches and are boiling six eggs, each of mass 60.2 g, in 0.850 L of water at 100C. You wish to take all the eggs out of the boiling water and immediately place them in 22.9C water to cool them down to a comfortable temperature to hold them and peel them. You decide that you wish the mixture of the water and the eggs to reach an equilibrium temperature of 40.2C. After explaining this to a family member, she challenges you to determine exactly how much water (in kg) you need at 22.9C to achieve your desired equilibrium temperature. Take the average specific heat of an egg over the expected temperature range to be 3.27 x 103 3/kg - C. You are working in your kitchen preparing lunch for your family.
