Conduction tranfer with the touche
Radiation transfer in distance
And convection moves as a current
<span>Well, during the day, the water, as well as the surfaces surrounding the water, are heated by various thermodynamic processes: conduction, convection, radiation, etc. This in turn warms the water molecules in the lakes, streams, rivers, and oceans, thereby transferring heat (their kinetic energy) to the water molecules, which in turn receive that energy from the surrounding surfaces, or directly via radiation/insolation from the sun. When the water molecules attain enough energy, some of them attain enough energy to escape the surface of the liquid and enter the gas phase. Hence, as water is heated, more and more water molecules attain enough kinetic energy to enter the gas phase.</span>
PH = - log [concentration of H+]
pH = - log [H+]
pH IS A MEAUSE OF ACIDITY AND BASIDITY OF A SUBSTANCE....
AS ACIDITY OF A SUBSTANCE DEPENDS ON THE IONISATION OF H+
THEREFORE IT IS A MEAUSE...
THE LOWER THE PH VALUE, THE MORE ACIDIC IS THE SUBSTANCE
Answer:
Distillation
Explanation:
A solution of water and ethanol are miscible. Hence, they can only be separated by a process known as distillation. Distillation is the process in which two or more constituents in a mixture are separated based on there difference in boiling points. <u>The mixture is subjected to high heat and the one with the least boiling point distills/evaporates out first followed by the next least boiling point</u>.
<u>From the explanation above, it can be deduced that ethanol (with boiling point of 78°) will be distilled out while water remains in the boiling tube or container</u>.
