Isochoric process apparatus
Installation for studying the isochoric process: a sealed tube with a pressure gauge allows you to check the pressure–temperature law at constant volume and estimate absolute zero.
The device consists of a body, a sealed tube, a piston rod with a locking mechanism and a pressure gauge. Fixing the piston sets a constant volume of gas, after which the pressure is measured at different temperatures. There are six experiments: qualitative verification of the dependence of pressure on temperature, verification of the pressure–temperature law at constant volume, plotting and determination of the thermal coefficient of pressure, extrapolation of an isochore to zero pressure with an estimate of absolute zero, an isochore in p–T coordinates and a family of isochores at different initial volumes. The apparatus is used when studying gas laws in a physics course.
