How hot is a sunspot (in Celsius)?
Sunspots are typically between 3000-4000 degrees Celsius. This is, relatively speaking, cool compared to the normal photosphere temperature of about 5500 degrees Celsius.
Paradoxically while the core of the red giant is contracting and heating up its radiation pressure causes its photosphere to swell up and cool off?
True.
Relatively cool stars look either orange or this color?
Red
What do you call a small faint relatively cool star?
If it is small and cool enough it could be a "brown dwarf". If it is a little warmer it is called a "Red Dwarf".
Where should a solar battery be stored?
Solar batteries should be stored in a cool dry place. This also extends the life of the battery. Batteries can also be stored in plastic battery storage containers. Keep in mind the storage area should be kept at or above 40 degrees to avoid capacity loss.
What is a loop of relatively cool gas that extends above the photosphere called?
solar flare
What is a loop of relatively cool incandescent gas that extends above the photosphere?
Nuclear fusion

Are dwarf stars relatively hot or cool?
cool
Paradoxically while the core of the red giant is contracting and heating up its radiation pressure causes its photosphere to swell up and cool off?
True.
Define sun spots?
Sunspots are areas on the sun's photosphere which appear black in telescopes. In actuality, they are bright but are cooler than the surrounding photosphere and so appear darker. They are magnetic storms on the surface of the sun, and the hot plasma is shunted towards either the negative or positive poles, thereby creating a 'cool spot' on the photosphere. These storms have an 11-year cycle which has yet to be well understood.
Is warm air above or below cool air?
Warm air is above cool air.
Is the asthenosphere relatively cool and rigid shell that overlies the lithosphere?
Yes, the cool and rigid shell is the asthenosphere.
Are compact fluorescent bulbs cool to the touch?
Relatively cool, yes, especially if you compare them with incandescent lightbulbs.
Relatively cool stars look either orange or this color?
Red
Is the asthenosphere a relatively cool and rigid shell that overlies the lithosphere?
Yes
What form the relatively cool brittle plates of plate tectonics?
The lithosphere.
