A piece of solid material of specific heat c unknown is weighed with a balance, m resulting in its mass. The piece is put in almost boiling water at temperature T.
M grams of water are put on the calorimeter, it is stirred and after a short time, its temperature T0 is measured.
The solid part is quickly deposited in the calorimeter. It is stirred, and after a certain time the equilibrium temperature Te is reached.
The data is recorded and c is cleared of the formula that's attached (please take a look).
<span>My only guess is obtain a metal and heat it in a boiling water bath (of known temperature) this will be your initial temperature. Now obtain a calorimeter cup with water of known temperature as well. Place the metal into the calorimeter cup and record the temperature after 5 minutes. You now have delta T, mass of the metal, and Q. Solve for C.
So yes! A mixture can contain just elements if those elements are not chemically reactive to one another. Air is a great example of an elemental mixture as it contains nitrogen, oxygen, and argon (along with some other compounds).
81. There is 1 carbon, 2 chlorine and fluorine atoms in Freon 12. To draw them it forms a cross with C in the middle and Cl and F both on the opposite side. Cl l F - C- F l Cl
82. Freon-12 and Freon-14 are called halocarbons or just halides.
