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).
Examples: Striking a match, combining vinegar and baking soda to form CO2 Gas, breaking light sticks releases chemical energy. R Radiant Energy - is a combination of heat and light energy. Light energy, like sound energy, travels out in all directions in waves. Examples: A light bulb, the glowing coils on a toaster, the sun, and even headlights on cars. e Electrical Energy - Energy produced by electrons moving through a substance is known as electrical energy.
