What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be?
Which condition causes storms to occur freezing of water droplets?
Which condition causes storms to occur freezing of water droplets? Cold Air Damming and Extended Lows Freezing rain develops when warm oceanic air rises up and over the cold air, producing liquid precipitation that falls through the cold layer. The falling droplets become supercooled and freeze on impact with the cold surface. Where is the […]
How is stoichiometric coefficient calculated?
How is stoichiometric coefficient calculated? Almost all stoichiometric problems can be solved in just four simple steps: Balance the equation. Convert units of a given substance to moles. Using the mole ratio, calculate the moles of substance yielded by the reaction. Convert moles of wanted substance to desired units. What is the stoichiometric coefficient? The […]
Can WD 40 spontaneously combust?
Can WD 40 spontaneously combust? If the oil will cure and harden, then it is a fire hazard. WD40 won’t spontaneously combust. At what temperature does gasoline vapor ignite? 536°F. Is it safe to pressurize gasoline? 100 PSI isn’t exactly a small amount of pressure and in itself is rather dangerous. If the container bursts […]
Why did the Hindenburg not use helium?
Why did the Hindenburg not use helium? U.S. law prevented the Hindenburg from using helium instead of hydrogen, which is flammable. After the crash of the hydrogen-filled R101, in which most of the crew died in the subsequent fire rather than the impact itself, Hindenburg designer Hugo Eckener sought to use helium, a non-flammable lifting […]
What are the 4 types of equilibrium?
What are the 4 types of equilibrium? There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples. Figure 1 presents a balanced system, such as the toy doll on the man’s hand, which has its center of gravity (cg) directly over the pivot, so that the torque of […]
Why do bubbles form in boiling water?
Why do bubbles form in boiling water? Boiling begins near the source of heat. When the pan bottom becomes hot enough, H2O molecules begin to break their bonds to their fellow molecules, turning from sloshy liquid to wispy gas. The result: hot pockets of water vapor, the long-awaited, boiling-up bubbles. Why does lower air pressure […]
