A chameleon sitting behind the shade of a rock has a surface

A chameleon sitting behind the shade of a rock has a surface body temperature of 20^degree C, matching the temperature of the ground and rock. After moving out of the shade, the chameleon warms in the Sun to 30^degree C. The chameleon then decides to change cooler, increasing its visible reflectance from 31% to 46%. Estimate the temperature the chameleon will reach as a result.

Solution

Chameleon change color to maintain their desire temperature they in shade become dark in color while under sun it turn pale in color which reflect light thus maintaining favorable temperature. They also change color during aggression, mating etc so color change does not depend solely on temperature
