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.
White light. Incoming light from the farthest stars is percieved as white, although the color might be lacking in absolute purity as a result of the gaseous content of the star. Scientists evalute the spectrum generated by the star to determine its speed and its make-up.
