A demonstration kit for studying atmospheric pressure
Overview: This instrument is designed for demonstrating thermodynamics in ordinary high school physics teaching. It can verify Boyle's law: when the temperature remains constant, the volume of a quantitative ideal gas is inversely proportional to the pressure it is subjected to. Product specifications 1. The diameter of the pressure gauge is 10 cm, and the unit is 0 atm, which is "standard atmospheric pressure". Positive pressure 1-4atm, negative pressure 1-0 atm. When 0 atm, it indicates that the interior is in a vacuum state; When the container is removed and ventilated, the pressure indicated by the pointer is the atmospheric pressure of the demonstration environment at that time. 2.The scale capacity of the container is 0 to 60 ml, with one graduation line per 1ml 3. The size is about 20 x12 x 31cm (the gas volume of the container is 50 ml). 4. There is a pipeline space between the 0 scale line and the pressure gauge, with a volume of about 10ml. When demonstrating, including it will obtain more accurate experimental data.
