A piece of metal weighing 59.047 g was heated to 100.0°C and then put it into 100.0 mL of water (initially at 23.7°C). The metal and water were allowed to come to an equilibrium temperature, determined to be 27.8°C. Assuming no heat lost to the environment, calculate the specific heat of the metal. 2 Specific Heat Capacity The amount of energy it takes to heat up 1 gram of a substance by 1 C What heats up faster, metal or water? 3 Calorie Energy changes can also be measured in calories. One calorie is defined as the amount of energy needed to increase the temperature of one gram of water...Step 1: Write the equation as it is usually given. Step 2: Because the unknown quantity—volume—is in the denominator, multiply both sides of the equation by volume (V). The equation will still be true, and volume will be on the left side where you want it. Step 3: Divide both sides of the equation by density (D). Heat Capacity Example Problem. Calculate the heat needed to raise water from freezing to boiling. What is the heat in calories? Useful information: specific heat of water = 4.18 J/g·°C Solution calories = 10450/4.18 calories x calories = 2500 calories Answer: 10450 J or 2500 calories of heat...leads to a feed molecular weight of 29.48, a feed mole fraction of O2 of 0.208 and a mass specific heat capacity of 0.25 kcal kg-1 K-1, which may be assumed to be constant.
