(2012 Nanjing model) shown in the figure for the "investigation of gas isothermal changes in the law" of the experimental setup, the pressure of the gas can be read from the meter, a section of air, the pressure of the gas can be read from the meter, the pressure of the gas can be read from the meter, the pressure of the gas can be read from the meter.
| During the experiment, the gas is compressed too fast, and the outside world does work on the gas, which raises the temperature of the gas. The gas leaks outward during the experiment, the mass decreases, and the product of the measured volume of the gas and the pressure becomes smaller |
