Leslie cubes

Uses

• Study of Emissivity: The different surfaces of the Leslie cube help demonstrate the concept of emissivity, which refers to how effectively a surface emits thermal radiation. For example, a black surface typically emits more heat radiation compared to a polished surface.
• Heat Transfer Demonstrations: By filling the cube with hot water, students can observe how heat is radiated from the different surfaces of the cube, helping them understand heat transfer mechanisms like radiation.
• Infrared Radiation Measurement: Infrared thermometers or sensors can be used to measure the radiation from each surface, showing how different materials and finishes radiate heat differently.
• Physics Education: Leslie cubes are a common tool in thermodynamics experiments to teach concepts like radiation, heat absorption, and temperature variation between materials.
