Adding heat (energy) to matter makes the particles move more quickly. Through these calculations, we determined that the heat transferred to the calorimeter water from the hot metal was 595.65J (6.0x10J with proper significant figures). Based off of the calculations, the obscure metal number one is zinc. Ini"al temperature of water is the room Then measure the mass of the water and reassemble, the calorimeter. Because of the Law of Conservation of energy which states that energy cannot, While waiting on the water to boil, retrieve a piece of unknown metal to be identified and record its ID letter and its mass. 5 Pages. Since faster moving things have more kinetic energy, adding heat increases the energy of the particle. Temperature was measured and distilled water was placed into the calorimeter, and after 2-3 minutes, boiling water was mixed in. though, weigh it accurately and record the mass on your data sheet. P31220 lab 1 Calorimetry Lab Purpose: Students . cup to mix the contents and record the temperature. The specific heat of water has the relatively high value of 4.184 J/gK.

Study with Quizlet and memorize flashcards containing terms like Beryllium is a rare metal that is gray in color, strong, and lightweight. I hypothesise the water heats ice to liquid and then goes to simmer and boil. We added the magnetic stirrer to the calorimeter and turned on the stirrer to a slow stirring rate. By comparing the data with the accepted heat capacities of various metals, the composition of the unknown samples was identified. This experiment was designed to determine the specific heat capacity of two unknown metal sample. Using the short fiber optic cable, record the O-scope display of the time between consecutive. MATERIALS. >> Course Hero is not sponsored or endorsed by any college or university. These are the countries currently available for verification, with more to come! When dealing with the transferring of heat and various process related to heat, the terms convection, conduction and radiation are frequently discussed thoroughly. The major result is that all of these experiments release energy because the calorimeter temperature increased. The relationship between the heat added, the mass of a substance, and the temperature change it undergoes is known as the specific heat. William Arndt. In the second experiment we found that the mass of the calorimeter and water with 50mls was 100.033g and the empty calorimeter was 50.857g. . We then measured out 50.0mL of heated deionized water into a graduated cylinder and placed a temperature probe in the graduated cylinder. It is assumed that the specific heat capacity is constant in the temperature range, although in reality it does vary with temperature., c. Use the formula in the background information to solve for the specific heat of the metal., To determine the specific heat of a metal and its approximate atomic mass. Skip to main content . 3.
