First of all it is important to note that heat and infra-red rays are NOT the same thing.
When an object gets really hot it starts to glow, emitting red light at first, (hence the phrase: 'red hot') because red is the least frequency. Hotter objects emit light of higher frequency. A light bulb and the Sun are both examples of this.
But infra-red rays are even lower in frequency than red light. Infra-red rays are emitted in the same way by objects at room temperature.
That means you, your computer and everything around you are 'glowing' with this infra-red radiation. Infra-red rays carry energy between objects at the speed of light. This process causes relatively hot objects to cool down faster.
What else can I help you with?
How do you transfer heat energy?
heat can be tranferred through, conduction, convection or radiation
If heat energy is tranferred away from an object what will the object feel?
radiation
How do you transfer energy?
heat can be tranferred through, conduction, convection or radiation
Is heat tranferred to human body during x raywhich form of heat transfer it is?
radiation
What is heat tranferred across empty space called?
Heat transferred across empty space is called radiation. Radiation does not require a medium to transport heat and can travel through a vacuum. It is how energy from the sun reaches the Earth.
Heat is tranferred by conduction when?
Conduction is tranferred by 2 object touching or getting close to eachother
Heat can be tranferred by?
conduction convection and radation
Body heat tranferred to the air by what?
Body heat is transferred to the air primarily through convection and radiation. Convection occurs as the warm air around the body rises and cooler air moves in to take its place, carrying away heat. Radiation involves the transfer of heat through electromagnetic waves from the body to the surrounding air.
How is energy tranferred between objects?
they have to go throw the atoms and then they go out throw the heat
How can heat be tranferred to areas?
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.
When heat tranfers by conduction?
Conduction is tranferred by 2 object touching or getting close to eachother
Another name for heat radiation?
INFRARED RADIATION is also referred to as Heat Radiation.
