Description:
【Product Identity】: This dedicated physics experiment kit is designed specifically for middle-school science classrooms to visually demonstrate the principles of thermodynamics.
【Primary Function】: Operating as a gas work demonstrator, the unit clearly illustrates how expanding gas performs work on its surroundings and experiences a decrease in internal energy.
【Key Features】: The adiabatic expansion apparatus features a thick-walled transparent cylindrical chamber, a secure rubber stopper, an internal container, and a clear rubber tube for easy observation.
【Practical Design】: Built for stability during classroom use, this demonstration apparatus is mounted on a sturdy black base with an upright black background panel that enhances visual contrast during experiments.
【Compact Dimensions】: This lightweight apparatus measures approximately 12 cm high, 12 cm deep, and 8 cm wide, weighing just 195 g for easy storage, setup, and transport between classrooms.
