Product Code : SCL-CELE-14035
This equipment is a self-contained unit designed to
demonstrate and verify Boyle's Law (Pressure is inversely proportional
to Volume). It allows for the precise measurement of the volume of a gas as its
pressure is intentionally varied, while the temperature is held constant.
1. Key Components and Design
The apparatus uses oil and sealed glass cylinders to contain
and adjust the gas volume and pressure.
- Measuring
Cylinder: A sealed glass cylinder where the experiment takes
place.
- Size: 100
mm diameter x 220 mm high.
- Function:
Contains a volume of gas trapped above a column of oil.
- Measurement: The
height of the oil, and thus the volume of the gas, is measured using a graduated
scale with a measured display height of 200 mm.
- Pressurizing
Cylinder: A second sealed glass cylinder connected to the
measuring cylinder.
- Function: Used
to adjust the pressure of the gas volume in the measuring
cylinder.
- Gas
Pressure Control:
- Compressor: A
small 500W electric compressor provides the means to adjust the
test gas pressure above and below atmospheric pressure.
- Safety: A pressure
switch and relief valves are included to ensure operator safety.
- Instrumentation:
- Compound
Gauge: Fitted to the measuring cylinder to measure the gas
pressure both above (gauge pressure) and below (vacuum)
atmospheric pressure.
- Thermometer:
Installed in the measuring cylinder to monitor and ensure the gas
temperature remains constant throughout the experiment.
2. Experimental Purpose
The primary goal is the verification of the pressure-volume
law for gases.
- Boyle's
Law Verification: Demonstrate that for a fixed mass of gas, the
product of its absolute pressure (P) and volume (V) remains constant (P
times V = constant) at constant temperature.
- Data
Collection: Collect corresponding data points of gas
pressure and gas volume across a range extending into both positive and
negative gauge pressures.
- Visual
Demonstration: Visually observe how the volume of the gas
decreases when pressure increases, and vice versa.
