In situ germplasm conservation is done by

In situ germplasm conservation is done by

A liquid-nitrogen container is made of a 1-cm thick styrofoam sheet having thermal conductivity 0.025Js^(-1)m^(-1)C^(-1) . Liquid nitrogen at 80K is kept in it. A total area of 0.80m^(2) is in contact with the liquid nitrogen. The atmospheric temperature is 300K . Calculate the rate of heat flow from the atmosphere to the liquid nitrogen.
