Three (3) adjacent bodies whose initial temperatures are 150°F, 350ºF and 60°F have specific heats of 2lb-ft/lb-°R, 4lb-ft/b-°R and 3.21lb-ft/lb-°R respectively. They are all placed inside a closed adiabatic (perfectly insulated) container until the equilibrium condition. If the first two (2) objects have a masses of 5lb, 3lb respectively, determine the mass of the 3rd body if the equilibrium temperature is attained at 87.5°F а. 39.22081b b. 41.4787lb c. 42.8977lb d. 39.7227lb
