Charles Law Apparatus
Charles’ Law Apparatus is a precision instrument designed to demonstrate the fundamental relationship between the volume of a gas and its absolute temperature, keeping pressure constant. This apparatus provides a clear and practical understanding of Charles’ Law (V ∝ T), making it an essential teaching aid for physics and chemistry laboratories.
Product Description:-
A Charles’ Law apparatus is a device used to demonstrate the relationship between the volume of a gas and its temperature at a constant pressure. It typically includes a capillary tube, thermometer, and a base plate with a scale.
A glass U tube, 15 mm dia, with one limb plain 220 mm long and other limb graduated 25 to 35 x 0.2 ml, 120 mm long terminating in a bulb 38 mm diameter, with third limb 185 x 6 mm (L x D) joined at right angles to the plane of the other two, short length of glass tubing mounted in end of wide bore plain limb with rubber bung, a piece of rubber tube and a pinch clip.
Supplied with tall form beaker 1000 ml and stirrer. 30 ml mercury is required. Supplied without mercury and without thermometer.
Features:-
- Transparent Graduated Tube – Accurately calibrated glass tube to measure changes in gas volume with temperature variation.
- Mercury/Water Reservoir – Ensures constant pressure during the experiment.
- High-Quality Construction – Made with durable glass and sturdy stand for safe and repeated use in labs.
- Easy Demonstration – Allows students to visually observe the expansion of gas with heating and contraction with cooling.
- Educational Value – Ideal for explaining gas laws, kinetic theory of gases, and real-life applications of thermodynamics.
