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.
Relatively cool stars look either orange or this color?
Red
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?
This phenomenon occurs because as the core contracts and heats up, more energy is produced and radiated outward. This increased radiation pressure pushes on the outer layers of the star, causing them to expand and cool down. As a result, the photosphere expands and cools even though the core is contracting and heating up.
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".

What is a loop of relatively cool incandescent gas that extends above the photosphere?
Nuclear fusion
What is a loop of relatively cool gas that extends above the photosphere called?

Are dwarf stars relatively hot or cool?
cool
What temperature is 2 Celsius?
2 degrees Celsius is relatively cool, equivalent to 35.6 degrees Fahrenheit. It is above freezing but still considered chilly.
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.
Relatively cool stars look either orange or this color?
Red
What form the relatively cool brittle plates of plate tectonics?
The lithosphere.
Would it be cool if your friend's dad had his own plane and flew you to New York?
Many people would consider that relatively cool.
Does granite cool below ground?
above
Is warm air above or below cool air?
Warm air is typically found above cool air due to the process of convection, where warm air rises and cool air sinks. This is why the upper atmosphere is warmer than the lower atmosphere in most cases.
