Temperature is an average value of energy for all the atoms and molecules in a given system. Temperature is independent of how much matter there is in the system. It is simply an average of the energy in the system.How is heat transferred?Heat can travel from one place to another in thr...
(b)Solar cells can be used to generate electricity. B(i) How is energy transferred from the Sun to a solar cell?(1) A by heating B by radiation C electrically D mechanically 相关知识点: 试题来源: 解析 BB (by radiation);A is incorrect because transfers by heatitng cannot take place ...
Radiation- obsorption is the process by which thermal energy is transferred through empty space. Home heating and cooling involve all three processes.CONVECTIONOne method of transferring thermal energy is to heat a substance and then allow the substance to move, carrying the thermal energy with it...
2.In your own words,describe a situation where heat is transferred in each of the following mechanisms:conduction,convection,radiation.ANSWER:1 conduction is the flow of internal energy from a place of higher temperature to one of lower temperature by the interaction of the adjacent objects ...
How is heat transferred? Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. As long as there is a temperature difference between two systems heat will always find a way to transfer from ...
Radiationis when heat is transferred through electromagnetic waves, such as from the sun. Radiation can transfer heat through empty space, while the other two methods require some form of matter-on-matter contact for the transfer. In order for two substances to affect each other, they must be...
What is heat (thermal energy)? Define and give two examples of electromagnetic radiation. Which part of the human body would be highly affected by a nuclear radiation first? Explain the effect of molecular size and motion on NOE (Nuclear Overhauser Effect). ...
The law implies that energy is naturally transferred from hotter to cooler bodies until equilibrium is reached. In simple terms, you suggest that your partner share their level of hotness with you for the two of you to be balanced and reach a mutual level of attraction. It's a unique way...
So, the quick answer is that while electromagnetic radiation can certainly be used to drive bond breaking, bond formation most often results in release of heat because photon emission usually just isn't competitive with energy transfer via collisions. The exception is the case in which the ...
In a ground-to-air or geothermal heating system, air is heated underground by the soil. Aside from having thermal energy itself, the soil absorbs a lot of heat from the sun because of its high thermal mass. So, you can heat air in underground pipes to pump back into the greenhouse once...
