NOas air is a fluid......the convection of air would bring the heat from your body
quicky.air is a poor insulator...and goose can trap the air ,in order to prevent
convection. therefore.. wearing clothers is better..

No. This is because the temperature as well as mass difference between the body and the atmosphere are very large and there is heat loss due to convention of air.
