In a pressure dependent system, two zones. on the same system are effected by the control of one. another. Example â. Room A and Room B are two conference rooms. Both. are supplied by different VAV terminal units from the. same central air supply.
The color of a star depends on its surface temperature. Our Sunâs surface temperature is about 6,000 Kelvin. Although it looks yellow from here on Earth, the light of the Sun would actually look very white from space. This white light coming off of the Sun is because its temperature is 6,000 Kelvin.
Cooler stars emit much of their light in the red part of the spectrum, so you see them as red. Somewhat hotter stars, like our Sun, emit much of their light in the green (or yellow), with smaller amounts of red and blue. This balance of colors your eye sees as white.
