A beaker of mass 325 g is sitting on a table. The beaker is filled with 210 g of water. The beaker and water are initially in thermal equilibrium at 22 ?C. An ice cube of mass 50 g, which was initially removed from an ice-water mixture, is dropped into the water, and the mixture is allowed to come to thermal equilibrium (assume the whole system is isolated). The equilibrium temperature is then measured to be 17 ?C. What is the specific heat of the beaker?
