Experimental Study on Ideal Gas Equation of State with Electric Heating

Experimental Overview

The ideal gas state equation, also known as the ideal gas law or the universal gas law, is a state equation that describes the relationship between pressure, volume, amount of matter, and temperature of an ideal gas in equilibrium. It is based on empirical laws such as Boyle Marius law, Charles law, and Gay Lussac law. This experiment verifies the ideal gas law by measuring the pressure p, volume V, and temperature T of a certain mass of gas sealed inside a transparent electric heating tube. This experimental device changes the volume of gas by rotating a large nut to move the piston, and uses a transparent electric heating tube to uniformly heat the gas to change its temperature. The gas inside the tube can be connected to the outside air or pressure sensor through a gas tube, and the temperature of the gas inside the tube is measured by a built-in temperature sensor.

The knowledge points involved in this experiment include the definition of ideal gases, the three fundamental laws, PID temperature control, temperature measurement, pressure measurement, volume measurement, etc. Through the experiment, students can develop a profound understanding of the relationship between temperature, pressure, and volume, as well as the ability to estimate and analyze measurement errors in thermodynamic quantities.
