5 The specific heats of aluminum and iron are 0.214 and 0.107 calories per gram degrees Celsius [cal/g °C)] respectively. If we add the same amount of energy to a cube of each material (of the same mass) and find that the temperature of the aluminum increases by 30 degrees Fahrenheit [F], how much will the iron temperature increase in degrees Fahrenheit [F]? esc 27 Click the icon to view conversion formulas for temperature scales. 28 Click the icon to view the factors for conversions involving temperature differences. 29 Click the icon to view the conversion table. 30 Click the icon to view the table of common derived units in the Sl system.
