Experiment work on Ideal Gas Law: Gay-Lussac

Topics covered:

- Ideal gas law PV = nRT

- Gay-Lussac's law

- Absolute temperature scale

- Absolute zero

Principles and objectives:

The ideal gas law governs the variables volume V (m3), pressure P (Pa), and temperature T (K) of a quantity n (mol) of a gas independently of its nature. It is expressed by the relation (1) below. R is a universal constant of ideal gases. PV = nRT

Gay-Lussac's law:

Gay-Lussac's law specifies that at constant volume, the

pressure of a given quantity of gas is proportional

to its temperature and vice versa. P and T will be measured with V and n constant, and the resulting relationship will be verified.

Comments:

The use of the ExAO Foxy range and the Scientific Workshop software suite makes the implementation of these experiments attractive, in addition to simplifying the setup and ensuring precision in measurements.
