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 ...
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. TTET between Os(bptpy)22+and BODIPY-Cb pro...
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–
(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...
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 ...
energy, inphysics, the capacity for doingwork. It may exist inpotential,kinetic,thermal, electrical,chemical,nuclear, or other various forms. There are, moreover,heatand work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always...
The electric energy can be transferred between different parks via an energy bus. This market enables the energy-rich parks to sell their surplus power to other parks at a favorable price, rather than to the external grid at a low price, and the energy-deficient parks to buy the power at...
The distance between two fluorophores can be obtained by Eq. 5, where Ro is the distance at which half the energy is transferred, referred to as the Förster radius, and r is the actual distance between the donor and acceptor. When calculating FRET, measurements are often taken at...
Missing electrons can be restituted before the chemical bonds are broken. In nuclear stopping processes the projectiles interact with the complete target atom and the target atom will be kicked out of the chemical surrounding if enough energy is transferred. Damage to the biomolecule is therefore ...
