Energy can be transferred from one form to another. For example, electrical energy can be converted into light energy. The word “into” in this sentence is a/an ___. A. prep B. conj C. verb D. adjective 相关知识点: 试题来源: 解析 A。“into”是介词,表示“到……里”,在这里表...
Heat,as a form of energy,cannot be created or destroyed.heat can be transferred from one substance to another.Heat always tends to pass from warmer objects to cooler ones.When a warm substance comes in contact with a cold substance,giving some of its energy to the cold molecules.This is ...
But do you know that energy can come from people, too? When you pedal a bike, you produce energy. You use your legs to push the pedals. Your energy is transferred (转移) to the bike. That makes the bike move. Now imagine riding your bike to create enough power to run a computer....
(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 ...
higher since heat can be transferred by radiation three advantage of using electric car than petrol car 1. electric vehicles have no emission 2. electric vehicles are quiet in operation3. electric vehicles are more energy efficient what other forms of energy would be generated during the breaking...
process (T1(PS)<S1(PD)) (Fig.1d). After applying NIR light and activating Os(bptpy)22+to the triplet state (1.69 eV), the photon energy can be transferred to the triplet state of BODIPY prodrug (1.51 eV) and trigger its photolysis....
This energy can be transferred either directly via heat exchangers (with or without physical separation) or indirectly through the heating of inert solid materials (such as high thermal capacity refractory materials which can then transfer the energy to low-temperature gaseous streams). The heat ...
Transfer of both chirality and energy information plays an important role in biological systems. Here we show a chiral donor π-gelator and assembled it with an achiral π-acceptor to see how chirality and energy can be transferred in a composite donor–
Besides, different energy forms could be gathered in an energy hub and transferred to other forms [18]. Electricity cannot be stored in large amounts. So, it can be converted to another form of energy firstly and then stored. Batteries, flywheels, compressed air energy storage, pumped ...
This structure is essentially a heat exchanger designed to convert the kinetic energy from the plasma into heat that is extracted by a coolant and transferred to a power turbine, which generates electricity in much the same way as a coal-, nuclear- or oil-fired electrical plant does. The ...
