Metal spoon

C. 3-Hydroxyquinoline. A 1-1. beaker is fitted with a thermometer and mechanical stirrer and clamped firmly on an efficient electric heater (Note 14). Diethyl succinate (400 ml.) (Note 15) is placed in the beaker and heated to boiling (215-220°) with stirring. 3-Hydroxycinchoninic acid (part B) (94.6 g., 0.5 mole) is added in portions to the boiling solution by means of a metal spoon or Scoopula. Care is taken to prevent too vigorous evolution of carbon dioxide. The addition requires 2-3 minutes, during which time a temperature drop is noted unless good heating is maintained. 

A wooden or plastic spoon, rather than a metal spoon, should be used to stir hot soup. Explain why, in terms of specific heat capacity. 

Paraphernalia associated with the use of heroin may also be encountered. These items include metal spoons, materials nsed in the process of dissolntion and heating heroin (candles, foil, etc.), materials nsed to filter the dissolved samples, snch as cotton wool, and items used for the injection of the solnbilized prodnct. All such materials should be treated with care due to the problems associated with needle-borne diseases. 

Moisture can sometimes be observed on a metal spoon held over a flame, but water will not be the only material observed on the spoon. There will also be soot. Combustion is usually not the clean, simple reaction outlined above. Combustion is usually a complicated conglomerate of many reactions in which fragments of hydrocarbons, or soot, are produced. Some of the most interesting behaviors of combustion reactions are a result of incomplete combustion and more complicated reactions. 

Heat can be conducted, or passed, through many types of matter. Metals are very good conductors of heat. The energy in heat conducts from one end of a piece of metal to the other end. This is why a metal spoon gets hot when only one end is touching the source of the heat. 

Conduction is the transfer of heat directly from one object to another. Conduction most easily and often occurs in solids but fluids may also transfer energy through conduction. For example, the metal spoon in a hot cup of coffee described in the previous skill will become warm because the hot coffee molecules touch and transfer their thermal energy to the spoon s atoms, warming the spoon s atoms.
