FAQ

Those who are looking for an answer to the question «Why do some areas of the photosphere become cooler than surrounding areas?» often ask the following questions:

❗ What are sunspots cooler than the surrounding areas?

  • Sunspots appear dark to us because they're cooler than the surrounding areas on the sun's visible surface, or photosphere , which has a temperature of about 10,000 degrees Fahrenheit (5,537.8 degrees Celsius ). The dark interior of a sunspot, called the umbra, is about 1,600 degrees cooler than the rest of the sun's surface.

❗ Why are sunspots cooler than the surrounding areas?

I'm not an astrophysicist but I know they are cooler because they are farther away from the source of heat than the surrounding area. The cause of a sun spot is probably excess heat. But as the spot, or eruption, climbs away from the sun it become cooler. It shows as black only because the lenses that are necessary to allow looking at the sun do not allow the smaller amount of light from a spot to be seen. Consider the room where you are. You may be able to see everything in it. But it is not all lit the same and if you put on a pair of sunglasses you might not be able to see areas where you could before. These areas are black, though they are still lit in actual fact.

❗ Are sunspot hotter or cooler than the surrounding areas?

Cooler.

Why are some video cards cooler than others?

  • Since these cards like to keep their heat to themselves, they can often be kept much cooler than custom cooler designs can when stacked closely together. However, the top card will tend to be a few degrees warmer. This is due to reduced access to airflow, and because the top card pulls up warm air from the back of the bottom video card.

Why do some seeds germinate in cooler weather than others?

  • The seed can also recognize swings in temperature. Ions in the soil are giving the seed clues to when it should break free and start to grow. Even as tiny seeds your plants have preferences. Seeds such as lettuce and peas germinate in cooler weather. Things such as peppers, tomatoes, and watermelons need warmer temps to germinate.

Why does the air from a fan's jet stream feel cooler than the surrounding environmental temperature?

Temperature is the same, but the stream of air takes more moisture off your skin then steady air. While doing that it effectively cools more your skin. As result you feel it as "cooler" air.

How does a warmer liquid become less dense than a cooler liquid?

The motion of molecules in matter increases with temperature. Molecular collisions in a warmer state have more energy than the collisions in a cooler state, tending to increase the volume and therefore reduce the density for a fixed mass.

Are dogs cooler than cats?

Well, you can't really answer this question because there are people who think dogs are better and then there are others who think cats are better.Answer:According to the Veterinary Information for Cats site, a cat's normal temperature ranges from 100.5 to 102.5 degrees Fahrenheit. The normal body temperature for dogs ranges between 99.5° to 102.5°F. So while dogs and cats may be the same temperature in some cases the potential for dogs to be slightly cooler does exist.
