A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
Phototrophism vs photosynthesis. Phototrophic organisms convert light energy into chemical energy in the form of ATP. The use of light energy to make ATP is called photophosphorylation. Photosynthetic organisms (photoautotrophs) also use light energy to make both ATP and reduced electron carriers (NADH or NADPH).
Light energy is the only visible form of energy . Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. In everyday we use the word âlightâ for at least 10 times a day!! Have you ever think about the energy we get from the light.
