Despite being so hot, the corona is less than a millionth as bright as the Sun. As you walk away from a bonfire, you feel less of its heat because you receive less energy due to the inverse square law. Why is the more distant corona so much hotter than parts of the Sun closer to...
as a result of the incessantly thermonuclear fusion processes that produce the energy the sun relies on. In general, the temperature decreases from the core to the photosphere and then increases towards the corona; however, the abnormally high temperature of the corona (~1 million kelvin) is st...
If 5.50 kJ of energy is required to heat up 0.04 \ kg of water from its initial temperature to a temperature of 320^o Kelvin, what was the initial temperature of the mass of water? How much heat is released when 25.0 g of wate...
According to Illinois law, it's pretty simple - if someone outside of the car can see what you're doing, it's illegal. So if you're driving around with your pants off and someone catches a glimpse, you could be in hot water. And no, putting on a show for other drivers on the ...
Auto white balance is often good enough, but if you want to make sure the colors in your shot don’t change, you can set it manually on some cameras. If your camera lets you adjust the Kelvin temperature for white balance, start at 5,600 (daylight) as a base, and then tune up (...
Most of the intergalactic medium is cold (about 2 degrees Kelvin), but X-ray observations suggest that some areas of it are hot (millions of degrees Kelvin) and rich in metals. One of the active areas of astronomical research today is directed at determining the nature of the intergalactic ...
"T" is the absolute temperature of the gas in Kelvin "R" is the ideal gas constant 0.0821 L-atm per mol-KAnswer and Explanation: Given: mass of oxygen = 100.0 g T = 100 C = 373.15 K P = 100 atm We begin by determining the amount in moles of O2...
Dark Matter Could Unlock a Limitless Energy Source The Source of All Consciousness May Be Black Holes Immortality Is Impossible Until We Beat Physics Is Consciousness Everywhere All at Once? One Particle Could Shatter Our Concept of Reality

However, using a custom white balance is the most accurate option. This way, you can input the exact value in degrees Kelvin. Alternatively, you can set it with a color-checker or a grey card. A light source with a small Kelvin degree has a yellow-orange color cast. This may be natur...
