Expert Solution

Step 1 Liquid Crystal Paper

Liquid Crystal Sheets are heat sensitive. It is used for doing exciting experiments.They change color based on the respective temperature. They can be read visually and quickly, at a distance. The sheets warm to the touch. They display the visible spectrum VIBGYOR when light falls on it, with blues and purple showing the warmest temperatures. If the temperature is too high, it will become dark. The color change happens due to tiny crystal layers on the micron scale and they twist as they warm.
