Abstract

North Bengal Science Centre, Siliguri, West Bengal, India National Council of Science Museums, Government of India Thermochromism is the reversible colour change of a compound when it is heated or cooled. The thermochromic colour change is distinguished by being quite noticeable, often dramatic and occurring over a small or sharp time interval. It is one of the important phenomena as it has bright future for industrial and practical use. North Bengal Science Centre regularly conducts Liquid Nitrogen Show to show the behavior of materials at low temperature to the visitors. During this time it is observed that ammonium dichromate shows thermochromism in liquid nitrogen.
