Specification
Brand : ERoomQ
BulletPoint1 : Purpose: This instrument is used for middle school physics teaching demonstration and student group experiment.
BulletPoint2 : Structure: 1. Outer copper (aluminum); 2. Cover frame; 3. Measuring cylinder (aluminum); 4. Thermal sleeve; 5. Wiring cover plug; 6. Wiring post; 7. Wiring rod; 8. Heating wire ; 9. Rubber stopper; 10. Cover stopper; 11. Stirrer
BulletPoint3 : (1) Determine the specific heat of the object; (2) Determine the electric heat equivalent.
BulletPoint4 : When the specific heat of the object is measured, the cover can be tested by replacing the cover plug on the cover frame. If you want to exchange the experiment to determine the electric heating equivalent, then replace the assembly with the heating wire for use, which is convenient and practical when changing the experiment.
BulletPoint5 : Technical requirements: 1. The heating wire is a nickel-chromium resistance wire with a resistance value of 2±0.1Q and 1±0.1Ω.

structure
1. Outer copper (aluminum); 2. Cover frame; 3. Measuring cylinder (aluminum); 4. Thermal sleeve; 5. Wiring cover plug; 6. Terminal; 7. Wiring rod; 8. Electric heating wire; 9 .Rubber stopper; 10. Cover stopper; 11. Stirrer

1. The heating wire is a nickel-chromium resistance wire with a resistance value of 2±0.1Q and 1±0.1Ω.
2. In the working state of the heating wire, the current is 1.7~2A, the voltage is 6, 100ML of water is passed for 10min, and the temperature rises to 10℃.
experimental method
Experiment (1) Experiment steps for determining the specific heat of objects:
1. Weigh the mass of the measuring cylinder of the calorimeter, fill the water to half full after heating, and then weigh it to find the quality of the water.
2. Put the measuring cylinder into the heat jacket to form a calorimeter, and measure the initial temperature of the water.
From the boiling water in the heating beaker, use tongs to quickly remove the metal cylinder and put it into the inner tube of the calorimeter, install the cover frame, gently stir up and down with a stirrer and measure its high temperature, that is, mixing After the temperature.
3. Take out the metal cylinder and wipe dry with filter paper, and weigh the quality.
After the experiment is completed, you can calculate according to the thermal stationary equation and substitute the data obtained from the experiment into the agenda formula:
