Dilatometer for liquids and gases
Product Code : SCL-MH-12790
The Dilatometer for Liquids and Gases by Educational Instrument India is a practical physics laboratory apparatus designed to demonstrate and study the thermal expansion of liquids and gases. It is widely used in school physics laboratories, college laboratories, STEM classrooms, and science demonstration labs for experiments related to heat, temperature, expansion, volume change, and gas behavior.
A dilatometer helps students observe how liquids and gases expand when heated and contract when cooled. The apparatus provides a clear and visual way to understand the effect of temperature on the volume of fluids and gases. It is especially useful for teaching concepts such as volumetric expansion, coefficient of expansion, thermal behavior of fluids, and the relationship between temperature and volume.
Designed for educational use, the Dilatometer for Liquids and Gases is easy to set up, simple to operate, and suitable for repeated classroom demonstrations. It helps teachers explain important heat and thermodynamics concepts through hands-on practical learning.
