Liquidsonsidered to present a state between solids and gases. The common thing with solids is that liquids have relatively small molar volume and high density. Due to repulsive intermolar forces liquids are hard to compress. However, in liquids there is thermal energy, which allows the molecules to slide o为敌 发表于 2025-3-27 04:40:15

Introduction/Vis) range. For natural reasons there is a long tradition in science of exploiting this range of wavelengths, particularly those of visible light. Indeed, the human eye was for a long time the principle instrument of observation in research and experimental work until the appearance of manmade dete组装 发表于 2025-3-27 22:19:19

Exploring the Insides of a Spectrophotometertion and matter. From a technical viewpoint this requires the generation of electromagnetic radiation, the modification of its characteristics and the control of its propagation through a given space. Similarly, the “fingerprints” which the material leaves on the radiation need to be producible in aDedication 发表于 2025-3-28 10:05:08
