Lab: Specific Heat. Page 2. Procedure: 1. If the hot plate you are sharing is not on, turn it on #8. The can should only have about 2” –. 2.5” of water in it. More water than that and you'll never get it to . Chemistry-1. Lab: Specific Heat. Page 4. Specific Heat Lab. Data: (Remember to write correct units!!) 1st Type of Substance: 22 Dec 2017 Full-text (PDF) | We discuss an experiment for determining the heat capacities of various solids based on a calorimetric approach where the solid vaporizes function.) Because the speeds vary for the longitudinal (c. l. ) and the doubly-degenerate transverse (c. t. ) waves, we write. g? ?d ? 4p . 2. 1. c. 3. The units of specific heat in SI are J / kg ?C. Historically, “specific” means “referred to water” and the measurements done in this experiment are referred to the specific heat of water. Thus, in this experiment we use as the unit of heat, not the conventional SI unit of energy, but rather the calorie. The calorie is defined as the Purpose: Using calorimetry, the specific heat capacity of a maetal and the latent heat of fusion of water are to be The method of mixing is used in the first experiment to determine the specific heat of a metal. Hot metal shot is Experiment 1: 1. Write the symbolic heat lost = heat gained equation for the process. Substitute. We discuss an experiment for determining the heat capacities of various solids based on a calorimetric and the doubly-degenerate transverse (ct) waves, we write dx ! : (6). The heat capacity from the Einstein model is straightforward to calculate, while a numerical integrator is required for. Eq. (6). III. THE EXPERIMENT. on the system, and heating or cooling occurs at constant pressure, this equation reduces to. dH = dQ (2). Using the relationship. dQ : CdT (3) we can then write If the mohg heat of evaporation of liquid N2 is known. (AHNZ ), then cg' simply follows from. EXPERIMENT. A simple evaporation calorimeter was fabricated from To determine the specific heat capacity of aluminium, iron and brass. from the definition, the specific heat of a given material can be determined In part (I) of this experiment an empty calorimeter at room temperature is filled with a known mass of hot water, then the mixture temperature is measured. So we may write heat but with a couple of important conditions. First, we have to b an approximation to Eq. 1. If the heat capacity does not dep. Eq. 2 is ?ne and will give us “the” heat capacity. But if the hea temperature in the range where the experiment is carried out, t. C will represent some kind of an average value. The second condition is even SPECIFIC HEAT. Pre-Lab Questions Page. 1. List the symbol and at least two units for specific heat. Hint: See equation 1 in the lab write- up. Page 2. THIS PAGE LEFT BLANK Page 3. OBJECTIVE: To determine the specific heat of various solids by the method of heat transfer. APPARTUS: Calorimeter Student experiment: Measuring specific heat capacities. Students should carry out an experiment to measure the specific heat capacity of a solid and/or a liquid very soon after meeting the expression. Allow the thermometer to reach thermal equilibrium and then write down the temperature. 3. Set up a suitable circuit that
