Calorimetry is a used to determine the gist of heat graft in a chemical reaction. It can measure mavin of two things: the amount of heat that is absorbed (in an endothermic process) or the amount that is gained (in an exothermic process). To conclude the calorimetry of a bosom, the equation below is used:
Eq. 1q= Cs x g x T
Q represents heat. Specific heat (Cs) is multiplied to the mass (g) and temperature trade that occurred in the reaction. ( T). Specific heat is defined as the amount of energy required to raise the temperature of 1 g of a substance by 1 K, under a continual pressure. Considering the fact that substances have differences, the specific heat varies depending on what substance is being heated.
Calorimetry is performed with a calorimeter. These can be intricate and pricey devices, but in this lab, two Styrofoam cups are used.
The purpose of this taste is to calculate the specific heat of a foreign metal. To do this, the metal will be heated, and then put into pissing to determine the heat transferred. The heat that is transferred from the metal to the water is mensural using the equation:
Eq. 2 q(water) = -q(metal)
The heat of water is verificatory because it was initially cold, and because the hot metal was being added to it, it gained heat.
The heat of the undiscovered metal is negative because of the loss of heat it is experiencing when submerged in cold water. The specific heat constant for water, 4.184 J/g C, is used for this equation.
The specific heat can be plant by using The Law of Dulong and Petit:
Eq. 3Cs(aluminum) = slope x 1/atomic weight
This equation is used to scram specific heat from the graph that will be displace based on the results of the metal specific heats.
