What is the efficiency principle?
This is an absolute principle, which can be applied universally and unconditionally. Efficiency principle: On a (nature) given amount of energy dissipation (by the thermodynamic supporting system) Q (this system naturally tend to) achieve the highest level and largest amount of (effective) information evolution X. This is the fundamental efficiency. All other efficiency derives from this efficiency.
What are all bodies emit called?
All objects and living things emit infrared radiation unless the object is not a black hole as well unless its temperature is not at the Absolute Zero ( I would call it an "infrared black hole") - such an object can only absorb 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.
What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
What temperature does an object emit electromagnetic radiation?
At absolute zero (O K or -273.15 degrees Celsius), there is no energy radiated. The wavelength of light emitted is related by Wien's Law: (lambda) = 3x10^-3/T Where lambda is the wavelength of the radiation. T is the temperature in Kelvin. When T approaches 0 K, the wavelength of the emitted radiation approaches infinity (lower energy). At zero, there is no emitted energy.
What is the definition of radiation use efficiency and light use efficiency?
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
When does Thermal radiation happen?
All the time. Thermal radiation is given off by anything above absolute zero.

What emit radiation?
anything hotter than absolute zero temperature
What types of matter does radiation happen in?
Electromagnetic radiation is emitted by all matter not at a temperature of absolute zero. Since it is impossible by both thermodynamics and quantum mechanics for any matter to be at a temperature of absolute zero, all matter emits electromagnetic radiation. If you were instead asking about radioactivity... only radioactive isotopes and highly energetic stellar and cosmological phenomena emit that.
All objects warmer than 0 kelvin absolute zero must be what?
Radiation electromagnetic energy
Why the inorganic substance not give infrared spectrum?
Any substance, organic or otherwise, will give off infra red radiation if it is above absolute zero. Even a substance that is absorbing radiation will emit some.
Which Philosophy in setting budgeted amounts assumes both the complete elimination of inefficiencies and a level of absolute efficiency?
The Zero-Based Budgeting philosophy assumes both the complete elimination of inefficiencies and a level of absolute efficiency. This approach requires each budgeted amount to start from zero, with every expense justified and approved based on its necessity and contribution to organizational goals.
What are the characteristics of the spectrum of the cosmic background radiation?
The measurements at a number of discrete frequencies of the background radiation that fills space place their relative amplitudes reasonably close to the curve that characterizes the radiation of a blackbody with a temperature of 2.725 degrees absolute. As such, the peak amplitude is found at the frequency of about 162.5 GHz.
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.
Can infrared radiation pass through glass windows?
That depends, short wave infrared radiation can travel through glass (hence the laser pointers and your TV remotes), but longer infrared waves get reflected. This is due to the design of glass so that we can see through it but the infrared heat radiation does not leave, thus improving efficiency.
How hot is it right now?
From several thousand degrees at the centre of stars to about three degrees above absolute zero in the background radiation. Take your pick
