Why do black clothes feel hotter than white clothes on sunny days?
Black clothes absorb more of the suns energy while white absorbs less. Since this energy is in the form of heat to us darker clothes feel hotter. EX) The sun emits photons of light. these photons have a characteristic wavelength to each color: blue green yellow red.....Black clothes absorb wavelengths of light from the sun that dont make up the black color, meaning they dont take in the black wavelength photons, just absorb the colors that dont make black color, like red and yellow. White clothes do not absorb any photons of the visible spectrum so they emit all the photons of light. Since they dont absorb the light energy from the sun they dont get as hot. But will still heat up but from the radiation of the sun.
Does thermal energy moves?
Such energy can be transferred. Usually it will transfer from hotter objects to colder objects.
Do hotter objects radiate more total energy per unit area than colder objects?
Yes
Do hotter objects emit more infrared radiation?
True , because the warmer objects give off more infrared radiation than cooler objects ..
Does yellow light have more energy than green light?
Yes. Blue light has a lower wavelength than yellow light, which is why it is perceived by out eyes as a different color. Blue light's wavelength is around 450 nanometers and yellow light's wavelength is around 575 nanometers. since the speed of light is constant for all light, and frequency is the speed of light over the wavelength of the light, the larger the wavelength, the lower the frequency. And the lower the frequency, the lower the energy. So the shorter wavelength of light (in this case, blue colored light) has a faster frequency, and therefore more energy.
Describe two ways in which the thermal radiation spectrum of an 8000 K star would differ from that of a 4000 K star?
First, the energy emitted at every wavelength is higher for the hotter star. Secondly, the peak wavelength of the hotter star is shorter than that of the 4000K one.
What is the relationship between the temperature of a radiating body and the wavelength it emits?
The temperature of the radiating body determines the intensity and characteristics of the radiation it emits. Two electromagnetic radiation principles describe the relationship between a radiating body�s temperature and the radiation it emits. 1. Stefan-Boltzmann�s Law: Hotter objects emit more total energy per unit area than colder objects. 2. Wein�s Displacement Law: The hotter the radiating body, the shorter the wavelength of maximum radiation.
Why are the hottest stars blue?
The hotter an object is the shorter the wavelength of light it emits as a shorter wavelength means more concentrated energy. Blue light has a shorter wavelength than most other colors, so the hottest stars are blue.
Which is hot a blue star or a red star and why?
All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.

Why does a star burn brighter when its hotter?
The star is hotter because the fusion process is more energetic, and photons are emitted as a result of fusion. So more energetic fusion...more energetic photons. On the electromagnetic spectrum, higher energy is to the right, which is the "brighter" end of the spectrum.
When objects get hotter what kind of energy do they have?
Thermal
Do objects gain energy when they are hot?
No, objects that gain energy become hotter.
What objects are relatively hot but not hotter than the Sun?
lightning is 5 times hotter than the sun.
Does thermal energy moves?
Such energy can be transferred. Usually it will transfer from hotter objects to colder objects.
Do the hottest bodies produce the shorter wavelenghts of maximum radiation?
Hotter bodies emit wavelengths which peak at the shorter end of the spectrum.
Does heat flow up to down?
No. Heat is not affected by gravity. Heat flows from hotter objects to colder objects.
