surface tension
when liquid evaporate, it turns into a gas. The evaporation process causes cooling on the surface of where the liqiud originated
When a substance goes from a solid to a liquid, it is melting. Generally, it is easier to heat an object that has more surface area because it has more area being exposed to heat.
Evaporation is sometimes called a surface phenomenon. The molecules on the surface of the liquid tend to suspend themselves in the atmosphere. To change these liquid molecules to gaseous form they require heat energy. They take energy called latent heat from the surrounding particles and thus change themselves to gas molecules. That is why evaporation is called surface phenomenon. As it takes latent heat from the surrounding particles it also causes cooling.
The relatively great surface area of a liquid drop impacts the evaporation rate. The greater the surface area, the greater the rate of evaporation. the converse is also true.
Increased surface area increases cooling. Cooling occurs by convection of air above the soup and water vapour loss.
Yes. Other things being equal, the cooling rate should be more or less proportional to the surface area.
The surface area of the liquid can decrease when there is increase in the temperature of the day,what is called evaporation is been taking place in the surface of the liquid,wchich decreases the liquid area.
put it in the fridge
If you pour it in a saucer, it will spread out and there is less surface area and it cools faster.

dear Sir, i have doubt about in frp bottle type and square type cooling tower, what is the calculation for calculat the contact surface area for assambled the fills. Regeards, raja

There is no such thing as "surface area" of "solubility" since the latter refers to the maximum concentration in the solution of a solid (or liquid) in a liquid. "Surface area", as applied to such a phenomenon is meaningless. However, by *increasing* the surface area of, say, a salt, by grinding it, will increase its solubility. Maybe *that* is what the questioner meant.
The principle of an air conditioner is evaporation of a liquid, that results in cooling, the same way sweat evaporating off your skin causes cooling. The difference is after the liquid evaporates it is returned back into a liquid state by compression. The fins that surround the tubes that this gas/liquid travels around in, are there to transmit the cooling into the air by increasing the surface area. If you don't vacuum these fins the cooling effect of the evaporation does not reach the air, so the a.c. has to run longer to cool the room and you. If you clean them it will significantly reduce your energy costs, so do it.
