What is potential energy released as?
What is potential energy released as? During this change, potential energy is converted to kinetic energy, which is the heat released in reactions. In an endothermic reaction the opposite occurs. The protons and electrons move from an area of low potential energy to an area of high. How do you describe stored energy? Stored energy […]
Which wavelengths of light are the most effective in photosynthesis?
Which wavelengths of light are the most effective in photosynthesis? The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges. What are colored molecules called? pigments. light-absorbing colored […]
