What are the three layers of soil profile? The main layers of the soil are topsoil, subsoil and the parent rock. Each layer has its own characteristics. These features of the layer of soil play a very important role in determining the use of the soil. Soil that has developed three layers, is mature soil. […]
Does the melting point increase across a period?
Does the melting point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from […]
What causes a comet to move?
What causes a comet to move? Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars and the galactic tide. Hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. How do I track comets? How to See Comet […]
Is Iron bad for copper pipes?
Is Iron bad for copper pipes? On cold-water piping, pitting and corrosion is often caused by an excess amount of flux residue. Iron deposits from a rusty water heater can also corrode copper pipes. What pH level is toxic? Toxic effects on survival, motility, and growth decreased with increasing pH. From pH 6.9 to 9.0, […]
Which wire has more resistance thick or thin?
Which wire has more resistance thick or thin? The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of the cross section of a wire is inversely proportional . Which wire produce […]
What is crystallization for Class 7th?
What is crystallization for Class 7th? Crystallization is a process by which a pure soluble substance separates out in the form of crystals from its hot and saturated solution on cooling. The process is employed in the separation of pure common salt from the impure common salt obtained from sea. What is the principle of […]
What is the major difference between simmering and poaching?
What is the major difference between simmering and poaching? Poaching is a technique typically used for delicate foods including eggs, fish and fruits. In order to poach food effectively, it must be completely submerged in water. Simmering requires the temperature of the liquid to be between 185 to 200 degrees. What food can be boiled? […]
How do I know my PNP and NPN sensor?
Is reduction Exergonic or Endergonic?
Is reduction Exergonic or Endergonic? The dehydrogenase enzyme reduces acetaldehyde to ethanol, which is an endergonic (energy-requiring) reaction: The reduction of acetaldehyde is coupled to the oxidation of NADH to NAD+, which is an exergonic reaction. Do oxidation and reduction always occur together? So oxidation and reduction always occur together; it is only mentally that […]
How does bullet kill?
How does bullet kill? Concentrated into a tiny surface area at the bullet tip, it can easily break through your skin. And once it does, that energy and momentum tears through your body, ripping a hole through blood vessels, muscle, and potentially vital organs. No wonder it can kill you. Does a headshot kill instantly? […]
