- Record the mass in the data table. Add about 10 mL of pure water to the test tube, and stir to dissolve the crystals. Obtain a 16-18 cm piece of Al wire. Use a small piece of steel wool to shine the wire and to remove any surface impurities that may be present on the wire.Measure and record the exact mass of the clean aluminum wire.Use tongs to lower the wire into the test tube containing the cupric chloride solution.The wire will extend beyond the height of the tube.easure and record the remaining mass of the dry Al wire in the data table. Repeat this experiment to obtain data for trial II using the other end of the Al wire. Allow the solid copper to dry overnight or place the containers in a drying oven or under a heat lamp for several hours.

How to Melt Aluminum This will stoke the fire and help increase the heat. Place the lid on the foundry and let it warm up. Let the foundry heat for about 10 minutes before placing aluminum inside of it. The temperature in the foundry will need to be above 1220 degrees Fahrenheit (660 degrees Celsius). Once the crucible is glowing orange, the foundry is hot enough to melt aluminum.

- At what temperature does aluminum turn into a solid? The scientific standard typically refers to the state change you refer to in terms of going up, so you need to know the melting point of aluminum to know when it becomes solid … , which is 933.47 Kelvin (660.32°C or 1220.58°F).luminum burns at over 4,100 K (6920°F), which is why it is used as a component of some solid rocket fuels. When it burns, it produces Al2O3 (alumina). Wow!

Aluminum has a specific heat of 0.900 J (g*C) how much energy in kJ is needed to raise the temp. of a 625 g? Best Answer: Specific Heat is the energy required to raise EACH gram of a material by 1C. This is expressed in J/gC. The temperature change is 82.1C - 30.7C = 51.4C. The Aluminum weighs, not 1g, but 625g. m x c x δT = Q 29.5g x 0.45J/g/°C x (40 - 25°C) δT = 199.125 Joules (= 0.199kJ) of heat absorbed. (you can say 0.200kJ) If 8.4kJ was used as in your initial statement, to raise the temp. by 5°C, the mass of iron must have been much greater than 29.5g. or, 8.4kJ is an error. 29.5 x 0.45 x 5 = 66.4 kJ.

- Introduction: The amount of heat energy that is required to raise the temperature of one gram of a substance by one degree Celsius is called the specific heat capacity, or simply the specific heat, of that substance. Water, for instance, has a specific heat of 1.0 cal / g • C o. Remember that the heat gained by the water is equal to the heat lost by the metal, calculate the specific heat of the metal. 2  This is simply rearranging formula (3) from the introduction to solve for the specific heat of the metal, and plugging-in your data.
