Some windows are made with a single pane of glass. Other windows are made out of two panes that have a tiny pocket of air trapped between them. The two diagrams below show how heat flows from a warm room to the outside air though both types of windows.
Considering that convection is driven by differences in temperature, double-pane windows are most likely used to
A.
create a convection current from the inside air to the outside air.
B.
create a convection current from the outside air to the inside air.
C.
decrease the rate of heat flow to the outside air.
D.
increase the rate of heat flow to the outside air.
