Apparatus for Demonstrating the Change of Aggregate States of Matter
Product Code : SCL-PL-11815
Apparatus for Demonstrating the Change of Aggregate States of Matter (SKU SCL-PL-11815) is a stand-mounted set with temperature sensors for following a substance as it melts, boils or solidifies, and for showing that temperature stays steady while the state changes. It suits Class 9 science and Class 11 physics lessons on heat. Science Lab Supplies manufactures the set in Ambala at Plot 448, HSIIDC Industrial Area, Saha, India, and ships it straight to schools, colleges, tender contractors and distributors.
Specifications
The apparatus combines a vertical stand and a tripod with triangular base, air temperature sensors reading from −30 to +135 °C with 0.1 °C resolution, five clips, a 500 ml glass beaker and five light bulbs, together with a demonstration table on changes of state.

Applications and Experiments for the Change of States Apparatus
The apparatus is used to record temperature against time while a substance changes state, producing heating and cooling curves with flat sections at the melting and boiling points. These plateaus introduce latent heat, making the set practical heat and thermodynamics lab equipment for schools and colleges.
- NCERT Class 9 science (Matter in Our Surroundings): melting point, boiling point and latent heat.
- NCERT Class 11 physics (Thermal Properties of Matter): change of state and latent heat.
- Plotting heating and cooling curves from sensor readings at 0.1 °C resolution.
- Middle-school science: solids, liquids and gases and how heating changes them.
Hot liquids and glassware are involved, so students should work under supervision and let the beaker cool before handling.
Standard Scope of Supply
Each set comprises the vertical stand, the air temperature sensors (−30 to +135 °C, 0.1 °C resolution), five clips, a 500 ml glass beaker, five light bulbs, the tripod with triangular base and the demonstration table. Test substances are not included and are chosen by the teacher.

Frequently Asked Questions
What temperature range do the sensors cover?
The air temperature sensors read from −30 °C to +135 °C with a resolution of 0.1 °C, which covers the melting of ice and the boiling of water.
What does the apparatus demonstrate?
It shows how a substance changes between solid, liquid and gas, and that temperature holds steady during melting or boiling while latent heat is absorbed.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is a manufacturer: the set is made in its Saha, Ambala works in India, and quotations are sent by the company directly.
Can the set be quoted for a school tender?
Yes. Send the quantity, delivery location and tender specification for an item-wise quotation built on the contents listed above.
