The temperature of the plasma gasses cools. This is because the gases lose some of their energy into light photons that disperse into space. When the plasma gases get cooler gases to become denser and sink to the bottom of the convection zone and are replaced from upwelling hotter plasma gas. The temperature at the bottom of the convection zone is approximately 200,000° C while that at the surface is 5700° C.
