Please answer this science question.?
At the Great Sand Dunes National Monument in Colorado, the visitors’ centre has a Trombe Wall. The wall is designed for passive solar energy collection. The air in the air gap is heated during the day by sunlight. This in turn heats up the masonry wall. The heat energy is then transferred to the visitors’ centre at night.
What is the method of heat transfer by which heat energy reaches the glass from the Sun?
and
How is the heat energy most likely to be transferred through the air gap? Explain your answer in terms of the density of air.
I think it is photovoltaic and
convection because the air is not as dense and the particles when heated bounce off each other travelling the heat along
ENERGY FROM THE SUN TRAVELS THROUGH SPACE AND AIR BY RADIATION, CALLED, STRANGELY ENOUGH, RADIANT ENERGY. IF THE AIR GAP IN YOUR QUESTION IS THE SPACE TWIX THE GLASS AND THE THROMBE WALL, RADIANT ENERGY WOULD BE THE GREATEST CONTRIBUTOR WHEN THE SUN IS SHINING ON THE WALL. CONVECTION IS HEAT TRANSFER DUE TO THE MOTIONS OF A FLUID, SUCH AS WARM AIR RISING. CONDUCTION IS HEAT TRANSFER THROUGH A SOLID, LIKE IF YOU TOUCH A HOT HANDLE ON A POT ON THE RANGE.
