States and properties of matter
Product Code : SCL-MH-12588
Unlock the foundational secrets of physical science with the States and Properties of Matter Demonstration Kit, precision-engineered by Educational Instrument India. Designed specifically for educational institutions, secondary schools, and collegiate physics or chemistry laboratories, this comprehensive kit bridges the gap between abstract kinetic molecular theories and tangible, real-world observations.
Matter is all around us, shifting dynamically between solid, liquid, and gaseous forms. This premium kit provides educators with a complete suite of robust laboratory instruments to visually demonstrate how thermal energy influences molecular spacing, intermolecular forces, and phase transitions. Students can explore core concepts such as thermal expansion in solids, the fluid mechanics of liquids, and the high compressibility and volumetric behavior of gases under varying pressures.
Curriculum-Aligned: Seamlessly matches physics and chemistry curriculum frameworks across CBSE, ICSE, IGCSE, and IB diplomas.
Hands-On Learning: Promotes active STEM learning, helping students retain complex conceptual definitions through experiential data collection.
E-A-T Certified Standards: Manufactured under strict ISO 9001:2015 quality control systems to ensure premium academic authority, safety, and precise calibration.
Constructed with highly durable, non-toxic materials, including heavy-duty borosilicate glass (3.3 coefficient) and anodized structural alloys, this kit is built to withstand rigorous daily classroom handling and repetitive experimental cycles over many academic terms.

- How to Use It: Step-by-Step Laboratory Guide
Activity 1: Demonstrating Thermal Expansion in Solids (Solid Phase)
Retrieve the brass Ball and Ring Apparatus from the protective foam casing.
Show students that at room temperature, the brass ball passes seamlessly through the matching brass ring.
Using a standard laboratory Bunsen burner or safe alcohol lamp, heat the solid brass ball evenly for approximately 60 to 90 seconds.
Attempt to pass the heated ball back through the ring. The ball will rest on top of the ring, vividly demonstrating thermal expansion as atomic vibrations increase its volumetric footprint.
Submerge the ball into a beaker of cold water to observe rapid cooling contraction; the ball will instantly drop through the ring again.
Activity 2: Verifying Gas Compressibility and Boyle's Law (Gaseous Phase)
Mount the Calibrated Gas Law Syringe onto its steady desktop baseplate.
Pull the plunger back to trap a fixed volume of ambient air inside the barrel (e.g., up to the 50 mL mark).
Securely twist the air-tight pressure cap onto the syringe nozzle tip to create a fully closed thermodynamic system.
Gradually apply weighted increments or manually press down on the plunger. Instruct students to observe how easily the volume reduces under increased external force, demonstrating the high compressibility and vast intermolecular spaces characteristic of gases.
Activity 3: Mapping Phase Changes & Latent Heat (Solid to Liquid to Gas)
Fill the Borosilicate Vaporization Flask halfway with crushed ice blocks and insert the High-Precision Digital Thermometer.
Place the flask onto a wire gauze tripod over a controlled heat source. Record the initial temperature (0°C).
Apply gentle heat. Observe that the temperature remains static during the phase transition from solid (ice) to liquid (water), visually illustrating latent heat of fusion.
Continue heating until the water reaches its rapid boiling point (100°C at sea level). Watch the energetic liquid particles escape as water vapor (gas), proving phase transformation boundaries.
- Frequently Asked Questions (FAQ)
Q1: Is this apparatus safe for middle school students to handle directly?
Ans: Yes, absolutely. Educational Instrument India prioritizes student safety. All structural elements are built with thick, break-resistant borosilicate glass and non-toxic coatings. However, experiments involving heat sources (like the Ball and Ring expansion or boiling phases) should always be conducted under continuous adult or instructor supervision.
Q2: Does this kit support standard educational curricula in India and abroad?
Ans: Yes. This kit has been specifically developed to satisfy the practical lab standards outlined in the NCERT/CBSE guidelines for Classes 6 to 10 science labs, as well as matching international practical testing criteria for ICSE, IGCSE, and IB Middle Years Programmes (MYP).
Q3: How should the kit components be cleaned and maintained after lab sessions?
Ans: Glassware should be washed using mild lab detergents and soft bristle brushes to avoid internal scratches. The metal elements (brass and aluminum) must be completely wiped dry with a lint-free cloth after use to prevent surface oxidation, then carefully returned to their custom-cut foam storage box.
Q4: Can we order individual replacement parts if a component accidentally breaks?
Ans: Yes. Educational Instrument India offers an extensive customer care program and a continuous inventory supply channel. You can reach out directly to our institutional sales department with your model number (EII-SPM-2026) to procure standalone replacement components anytime.
