Do hot objects absorb infrared radiation?
All objects emit (give out) and absorb (take in) thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits. However; the hotter an object, the faster it will emit infrared radiation. Even though hotter objects can absorb infrared radiation, they will continue to emit infrared radiation much faster than they absorb it from any colder objects / sources around them, until an equilibrium is achieved with the objects surroundings i.e. it is always an antagonistic relationship with the objects surroundings and the surroundings with the object.
Do hotter objects emit more infrared radiation?
True , because the warmer objects give off more infrared radiation than cooler objects ..
How does infrared light reflect off objects?
Infrared radiation or light is part of the electromagnetic spectrum and acts the same as visible light does.Infrared can be absorbed and reflected by objects much the same way as visible light. More on Infrared:Some black objects that absorb visible light radiation may reflect infrared.Much of the absorbed visible light energy is re-emitted as infrared up to many hours later.There are subcategories of infrared, two common ones are near-infrared and far-infrared. Near being closer to visible light.
What would happen if gases absorbs visible light?
Earth's atmosphere does have greenhouse gases. These gases absorb some of the infrared radiation emitted by Earth's surface. If it did not, Earth would grow warmer and warmer as it absorbed more and more solar radiation. Greenhouse gas molecules absorb and emit infrared radiation.
Does infrared change the temperature of glass?
Yes, infrared radiation can change the temperature of glass. Heat (thermal) energy moves by conduction (touching), convection (hot fluids moving around cooler objects or vice versa), and by radiation. Let's look more closely. Infrared radiation is exchanged by all objects all the time. Compared to some kind of background temperature, cooler objects tend to hang on to more of the thermal energy arriving by infrared radiation while warmer objects tend to radiate more of that energy. A cooler glass sitting on a counter in a warm room will eventually collect thermal energy (and probably by both convection and radiation) until it warms to room temperature. Likewise a hot glass will cool to room temperature by the same method.

What types of objects emit of infrared raditation?
Any object emits infrared radiation. The hotter the object, the more infrared is emitted.

Which object emits the most radiation of these 4. Water dirt fir or ice?
It isn't clear what sort of radiation you are talking about. If you mean infrared radiation, if the temperature is the same, darker objects do tend to emit more radiation.
Why do light coloured objects reflect radiation more than dark coloured objects?
Because dark colours absorbs light, and energy;and its named absortion coefficient. ============================== Some substances and objects made from them reflect more light and absorb less. Other substances and objects made from them reflect less light and absorb more. The ones that reflect more and absorb less are the ones that appear lighter to us. Why ? Because they absorb less light and reflect more of it toward our eyes.
What determines if a gas can be categorized as a greenhouse gas?
If a gas has three or more atoms, then it can vibrate and absorb the heat/light from the infrared radiation coming from the warm earth and clouds.
How do opaque objects reduce the transfer of heat by radiation?
because black things absorb more heat and white things reflect it
Do x ray radiation photons have more engery than infrared waves?
yes, x ray radiation photons have more energy than infrared waves
What processes produce the difference colors we see in opaque objects?
Different materials absorb different wavelengths of visible radiation from sources like the sun or light bulbs. The wavelengths that are not absorbed are reflected as visible radiation, and the color we see depends on the wavelength of that reflected light, with a longer wavelength correlating to more reddish colors, and shorter wavelengths with more bluish colors. White objects reflect all of the visible radiation that strike them, which is why they absorb less heat than black objects, which reflect much less visible radiation.
