An aluminum cube of mass 44.25 g is immersed in liquid Nitrogen and comes to thermal equilibrium with the liquid Nitrogen. This equilibrium temperature is that of liquid Nitrogen, -195.8° C. The cube is then immersed in 189.47 g of water at 22.3° C. The final, equilibrium temperature of the water-aluminum cube system is 14.0° C. Calculate the specific heat of the aluminum cube. Answer should be in units of calories, grams and °C. Show formulas and calculations.
