Physics Lab Report
Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 |
Instructor: Mr. Nailer |
I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT), its mass (m), and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose
The purpose of this laboratory is to determine the experimental quantities of heat transfer and specific heat capacity in a laboratory situation..
III. Equipment * Eye protection * Graduated cylinder * Thermometer * Stirring rod * 250 mL beaker * Retort stand * Ring clamp * Hot plant * 100g brass object * Tongs * 2 Styrofoam cups IV. Experimental Procedure * Part A: Determining Heat Exchange 1. Put on your eye protection. 2. Use a graduated cylinder to measure 100 mL of cold tap water and place it in a Styrofoam cup. Measure and record the temperature of the cold water in a copy of Table 1. 3. Measure 100 mL of hot tap water and place it in a separate Styrofoam cup. Measure and record the temperature of the hot water in Table 1. 4. Pour the cold water into the hot water. Put the thermometer in the cup and use the stirring rod to mix the water. Watch the temperature carefully and record the highest temperature reached in table 1. * Part B: Determining the Specific Heat Capacity of Brass 1. Place the hot plate on a retort stand with a ring clamp. The ring clamp should be positioned so that the top of the beaker is held in place by the ring. 2. Fill the 250 mL beaker one third full with tap water. Place it inside the ring over the hot plate. 3. Use the balance to measure the mass of 100g brass object and record the mass in a copy of Table 2. 4. Place the brass object in the beaker of water on the hot plate. Turn on the hot
