Heat can be transferred through three methods: radiation, conduction and convection.
Radiation is when heat is transferred through infra red radiation. This can be absorbed by water.
Conduction in when heat energy is transferred between touching materials. If you heat the end of a metal pipe the heat will travel up the pipe through conduction. Materials like metal are much better at conducting heat than insulators like wood.
Convection refers to when a gas or liquid moves as a result of being at a different temperature to the surrounding gas or liquid. Under tectonic plates the magma moves because of convection currents created by the fission at the earth's core (as opposed to fusion in the sun). If you put a heater in a corner of a room the air is circulated by convection currents caused when the hot air rises, cools and then falls back down again.
If this doesn't help then try the links I've added in the links section of this question. If it did help then why not recommend me (Kittsville).
The object is warmed by the "heat" created when the infrared wave strikes the object. The type of material in the object determines how long this heat is stored and how fast is gives the heat away (latent heat)
the energy goes the other planets the energy goes the other planets
It is true that when an object absorbs light the light energy that is created is usually changed to heat. This was a theory that was proven by Sir Isaac newton.
The thermal energy of an object that absorbs light energy is increased. This is because light and heat are forms of energy, thus absorbing light will produce an increase in thermal energy.

Do all objects radiate energy?
yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in. yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in.
The silvered wall of a vacuum bottle takes care of heat flow by?
There is a silvering in the vacuum flask in order to reduce the loss of heat through the means of radiation.
Does a cold object still have heat?
Yes, it still has some amount of internal energy or "heat". Even considering the coldest objects in the universe, it is still impossible for an object to have no heat, and this theoretical state is known as absolute zero.
Part of the electromagnetic spectrum makes the sidewalk feel warm on a sunny day?
The sun emits all of the electromagnetic spectrum. The part that heats the sidewalk is the infrared region which is invisible and has a long wavelength. Dark objects absorb much more heat than lighter objects so that asphalt pavement will get much hotter than concrete.
What is a substance that dose not transmit light?
An opaque object does not reflect light. Opaque objects absorb light.
Do all objects absorb infra red radiation?
No, not all objects absorb infrared radiation. The ability of an object to absorb infrared radiation depends on its material properties. Different materials have different levels of absorption and reflection of infrared radiation.
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 hot objects absorb more infrared radiation?
Yes, hot objects emit more infrared radiation compared to cooler objects. The amount of infrared radiation absorbed by an object depends on its temperature and the material properties of the object. Generally, hotter objects have more thermal energy to emit and absorb more infrared radiation.
What heat is transferred through infrared lamps?
Infrared lamps emit infrared radiation, which is a form of electromagnetic radiation. This radiation transfers heat energy to objects or surfaces that absorb it, causing them to warm up. This heat transfer is efficient because infrared radiation can penetrate the air without heating it, directly warming the targeted objects.
Do all molecules absorb infrared radiation?
No, not all molecules absorb infrared radiation. Only molecules with specific molecular vibrations that match the energy of infrared radiation can absorb it. These vibrations involve changes in dipole moment or stretching/bending of bonds.
Are black surfaces are good reflectors of infra red radiation?
No, black surfaces are actually poor reflectors of infrared radiation. They absorb more infrared radiation compared to other colors, which is why black objects often feel warmer in sunlight. White surfaces are better reflectors of infrared radiation.
Is white paper a best absorber of infrared radiation?
No, white paper is not the best absorber of infrared radiation. Darker objects, like black paper or materials with dark pigments, tend to absorb more infrared radiation because they reflect less of it compared to white surfaces.
What does carbon dioxide and water vapor absorb?
Carbon dioxide and water vapor absorb infrared radiation from the sun and the Earth's surface, contributing to the greenhouse effect and trapping heat in the atmosphere.
Does bright red absorb heat?
Yes, bright red objects can absorb heat because they absorb light across a broad spectrum, including infrared radiation, which carries heat. The absorption of light energy by bright red objects causes them to heat up.
What does water absorb?
IR Radiation otherwise known as Infrared Radiation or heat energy
Can infrared radiation be stopped by materials?
Yes, infrared radiation can be blocked by materials that are opaque to it, such as metal foils, dense fabrics, and certain plastics. These materials absorb or reflect the infrared radiation, preventing it from passing through.
Do black surfaces absorb infrared well?
Yes, black surfaces absorb infrared radiation well because they are able to absorb a broad spectrum of wavelengths, including infrared. The dark color of black surfaces allows them to efficiently absorb and retain heat from infrared sources.
