ASea and land breeze
BBoiling of water
CWarming of glass of bulb due to filament

Heat Transfer

A double-plane window consist of two glass sheets each of area $$1m^2$$ and thickness $$0.01m$$ separated by a $$0.05m$$ thick stagnant air space In the steady state, the room glass interface and the glass outdoor interface are at constant temperature of $$27^oC$$ and $$0^oC$$ respectively. The rate of heat flow through the window plane is (Given , $$k_{glass}=0.8\,\,W\,\,m^{-1}K^{-1},K_{air}=0.08\,\,W\,\,m^{-1}K^{-1})$$
