Negative adsorption occurs when the concentration of the adsorbate is less on the surface of the adsorbent as compared to the concentration of adsorbate in the bulk of the solution. Absorption is the process when the solute is uniformly distributed in the bulk of the solvent.

Adsorption is a phenomenon wherein the local concentration of a substance at the surface of a solid or liquid becomes greater than the concentration throughout the bulk. There are two types of adsorption: Physical adsorption and Chemisorption.

In absorption, the atoms enter into the bulk phase of a liquid or solid whereas adsorption substances adhere to the surface of the molecule.

Adsorption is an exothermic process since surface particles of the adsorbent are unstable and when the adsorbate is adsorbed on the surface, the energy of adsorbent decreases, and this results in the evolution of heat. Therefore, adsorption is always exothermic.

When heat is absorbed by the solution, q for the solution has a positive value. This means that the reaction produces heat for the solution to absorb and q for the reaction is negative. When heat is absorbed from the solution q for the solution has a negative value.

Real life examples of reflections are: the symmetry of your face, a butterfly, an airplane and so many more objects. mass production of shoes and spectacle frames. flipping images on a computer.

Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye.

Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. Not all the light energy from the sun is absorbed. Sunlight has many different colors in it. Chlorophyll usually absorbs red and blue light from the sun and reflects green light.

Saturated sand has a thermal conductivity in the range of 2-4 W/m-K which causes the sand layer thickness to go astronomical. Thus it can be shown that sand is a good replacement for fiberglass pipe insulation in underground, direct buried applications.

Sand is a solid and a poor conductor of heat. That means that when sunlight hits sand, all the energy of the sunlight is absorbed in the first millimeter or so of the sand, the heat stays there or spreads only a few millimeters down. So those few millimeters get quite hot.

Answer and Explanation: Yes, sand conducts heat better than water because the molecules in the sand are closer together than the molecules in water.

about 0.08 to 0.11 per inch

Sand is a terrible conductor of electricity. Things don’t have to be very conductive to conduct from sources of billions to trillions of volts.

This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely.

Saltwater is a good conductor of electricity because it is an electrolyte solution. Substances such as salts, acids and hydroxides that also are electrolytes can conduct electric current. Saltwater is a mixture that consists of water and sodium chloride.

While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density.

Answer. Lemon juice contains citric acid. Because acids break up into charged anions and cations when dissolved in water, they conduct electricity because the charged particles are able to flow within the acid. -Therefore,it is good conductor.
