Description
This convection in air apparatus is a hands-on STEM demonstrator for heat transfer in gases. A candle heats the air inside the chamber, warm air rises up one chimney while cooler air flows down the other chimney to replace it. With a smoke source and a dark background, the moving convection currents can be seen clearly, making it easier for students to connect the model to real situations such as air-conditioning airflow, building fire drafts, and wind direction changes near beaches.
Includes a metal box with an acrylic front panel and two acrylic chimneys. Smoke source required.
Unpacking and setup: Slide the front panel out to access the two acrylic chimneys.
FAQs
Q: What heat transfer process does this demonstrate?
