Adsorption is the process by which a substance in a gas or liquid becomes attached to the surface of a solid. Some examples are the ocean adsorbing carbon dioxide in the atmosphere and the adsorbing of non edible particles to bone used to stir food mixtures by early humans.

∙ 9y agoNatural methods of adsorption take place all the time. For example, the ocean adsorbs carbon dioxide in the atmosphere, which effects climate and atmospheric temperature. Also, early humans observed that if they charred a piece of bone all the way through, they could put the bone in food mixtures, like sugar water, and it would collect polluting particles that weren't edible thus purifying the food.

∙ 14y agoIt is used for separation of gases,based on the differences in the adsorption of gases on adsorbent at different temperature.Example : mixture of noble gases can be separated usin activated charcoal. Silica and alumina gels are used as adsorbents for removing moisture and for controlling humidities of room. Adsorption also plays an important role in heterogeneous catalysis,eg use of finely divided Fe in the manufacture of ammonia and that of finely divided Ni in the hydrogenation of oils. Activated charcoal is used in gas masks in which all toxic gasas and vapour are adsorbed by the charcoal while pure air passes through its pores practically unchanged.

Do diamonds have effervescence?
In the strictest definition, chemically, diamonds do not effervesce -- give off gas. However, visually, one could describe a diamond as vivacious, which is another definition of the word you wrote.
How do you calculate molecular weight of a compound from its langmuir isotherm?
The monolayer capacity of the adsorbent is equal to number of moles of adsorption sites present on one gram of sample. The Langmuir and BET isotherms may be used to find th monolayer capacity of the adsorbent. Thus on taking the reciprocal of the monolayer capacity, one can find the molecular weight of the adsorbent.

In ballet describe one element of time used in dance and also describe 2 adjectives that describe energy of ballet and give an example of what type of movement this is seen?
an element of time used in dance would be the waltz. i think 2 adjectives that would describe the energy of ballet would be graceful, and beautiful. an example of the type of movement through which this can be seen i would say would be grand jetes (or big leaps in the air)
