How many atoms are in a element? 2.8. Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in […]
Is Second Law of Thermodynamics true?
Is Second Law of Thermodynamics true? The laws of thermodynamics only hold true as statistical averages, and some think the second law won’t be so cast-iron on the very small scales of quantum physics where few particles are involved. Some physicists even think quantum machines might bend the rules or cause them to be cast […]

Which factors or processes drive the movement of air in Hadley cells?
Which factors or processes drive the movement of air in Hadley cells? Which factors or processes drive the movement of air in Hadley cells? -Cool, dry air falls towards the surface of the Earth, where increased air pressure causes adiabatic heating, resulting in warm, dry air. What drives the movement of polar cells? The polar […]
What keeps a car from overheating?
What keeps a car from overheating? The best way to prevent an overheating car engine is to have regular coolant flushes and exchanges performed on your car, and stay up-to-date with radiator maintenance as recommended by your vehicle manufacturer. Routine inspections can also help you fix any potential radiator or engine issues before they worsen. […]
Which is least stable Carbocation?
Which is least stable Carbocation? -Hence, out of the given options, the carbocation that has the least number of substituents is CH3−CH2−+CH2. So, it will be the least stable species. Why vinyl cation is unstable? The vinyl cations are less stable due to the difference in hybridization of the carbon bearing the positive charge. Since […]

What is the soft weak and plastic like layer?
What is the soft weak and plastic like layer? The movement of the lithospheric plates is facilitated by a soft, weak and plastic-like layer is called asthenosphere. Do the plates in this activity have the same density? Answer. Answer: Explanation: They are denser compared to continental crust, meaning they have more mass per unit volume. […]
