Why evaporation is a cooling process?
according to kinetic theory,the temperature is a measure of average kinetic energy of the molecules of a liquid.during evaporation,the escape of high energy molecules from the surface of a liquid,lowers the average kinetic energy of the remaining molecules and therefore,the temperature of the liquids falls down.thus evaporation is a cooling process.

What causes the change of state?
A simplistic summary of a very complex process would be: As heat is added to a solid material matrix, the kinetic energy of its molecules becomes greater than the intermolecular forces that hold those molecules. With this a change in phase occurs. For example, in a solid crystal, the molecules are held rigidly in position by the intermolecular forces. As the heat of the matrix increases, the molecules become more energetic and the movement around their equilibrium positions becomes faster and larger. Eventually, their enhanced motion permits them to create spaces in the crystal that other molecules can move into - the solid has now become a liquid (a different phase). As the heat increases even more, the increased kinetic energy of the molecules allows them to completely overcome any intermolecular forces and atmospheric pressure, and the material begins to become a gas and escapes the matrix. Cooling (removing heat) from a gas to allow condensation and then crystallization is the opposite process.

What happens to eggs when cooked?
When eggs are cooked they go through a chemical process, a irreversible process. Eggs have protein molecules, and protein molecules change shape when you heat them. The energy which is given through cooking (kinetic energy for the molecules) breaks some of the chemical bonds (also could be known as an intermolecular bond or a covalent bond) in the protein and this allows the molecules to take a different shape. This gives the food a more edible texture. This change is irreversible. It's called denaturing.

How does heat energy travel through solids by conduction?
Generally: Heat Energy is the external manifestation of the Internal Kinetic Energy of the Molecules of any matter. However, these molecules due to their Kinetic energy all always in Random Motion. Now Answer to what u Have asked : 1. If we supply some heat energy from external source it imparts kinetic energy to the molecules of the solid Conductor which in turn start vibrating violently. This process works like a chain and energy gets imparted from one to next and Son on.... In this way Heat Energy is Transferred through Solids. Since the Intermolecular space is quite less in case of Solids, So this process is hurried.

Process that occurs during boiling?
The process that occurs during boiling of liquid is energizing of water molecules (H2O) to give them excessive energy for excitement to change their form to gas from liquid. This energy can be provided by heating and electric current. In the liquid state, atoms and molecules are bound together by strong intermolecular forces as compared to gases.While boiling a liquid we provide heat to the molecules whereby their kinetic energy is enhanced and they now have enough energy to overcome the cohesive forces and escape from the liquid surface hence changing into gas.This process is called evaporation.
What is the flow of energy from a warmer object to a cooler object?
Molecules in warmer object will have more average kinetic energy of molecules compared to the molecules in cooler object. Therefore the energy will be transferred from the region of more to kinetic energy to a region of low kinetic energy of molecules until equilibrium is reached between both the objects. This is similar to the process of diffusion which dictates the flow of solute molecules from an area of its high concentration to an area of its low concentration.

How is evaporation and boiling different?
In both cases, a phase change from liquid to gas occurs. evaporation normally is associated with a slow process where the liquid molecules, usually on or near the surface of the liquid, gain sufficient energy to overcome atmospheric pressure and the intermolecular forces of the liquid and escape as individual molecules of gas. boiling is usually a more rapid process involving the addition of heat to the liquid until the temperature is = to the boiling point of the liquid. At this point, the vapor pressure overcomes atmospheric pressure and intermolecular forces. In this condition, the liquid molecules not only at or near the surface, but also those within the liquid bulk, begin to vaporize. The result is the familiar bubbles of a boiling liquid. The bubbles are, of course, gas bubbles that escape the liquid as they breach the surface.
Asked in Water Fountains and Ponds
What is the process called when water leaves ponds into the atmosphere and back to the ponds?
Vaporization (aka. evaporation) is the process in which the molecules in liquid water break their intermolecular forces of attraction and become gas molecules. These H2O gas molecules have no where to go, except into the atmosphere. So the process for when these gas molecules change back into liquid molecules and leave the atmosphere, (or when it rains) is called condensation. This water of course goes back into different water sources such as ponds, lakes, and oceans.

How can a soild be changed to a gas?
Most substances are changed from solid to liquid to gas by heating until the intermolecular forces are overcome by the kinetic energy of the molecules. In some cases, a compound can be changed directly from a solid to a gas in a process called sublimation. This can occur if the atmospheric pressure exerted on the substance is too low to stop the molecules from escaping from the solid state. Common examples of this are dry ice (solid CO2) converting to a vapor, or the process of freeze drying, which causes the sublimation of water.
How do hydrophilic substances interact with water?
hydrophilic substances are electrically polar in character, they possess a dipole. Intermolecular forces associated with this polarity attract (or are attracted by) the polar water molecules. Having sufficient energy, the water molecules can interpose themselves between and eventually surround the hydrophilic substance thus reducing the repulsive intermolecular forces acting between these hydrophilic molecules in their pure state... Energy and Entropy effects are driving the process...

What process involves a liquid changing to a gas only at its surface?
Asked in Human Anatomy and Physiology
What is the process by which substances scatter themselves throughout an available space?
The process is called as diffusion, probably. The molecules have kinetic energy. that makes them to diffuse probably. Why the molecules do not come closer to each other, due to gravity is a question mark. Probably the kinetic energy is more powerful than the gravitational force. If you mix two gases, they will diffuse evenly in the space. How and why this happens is the question mark, again.
Do molecules gain or lose thermal energy while evaporating?
Asked in Osmosis
What is the relation between osmosis and temperature?
Osmosis is a soluble (liquid) traveling through semi permeable membrane which is a wall that only allow certain cells and molecules through. So if temperature is low, kinetic energy is low and H2O molecules will slow down. While if temperature is higher, kinetic energy is more and H2O molecules will move faster thus the speed of the process of osmosis increases.

Asked in Chemistry
How do temperature and pressure affect solubility?
The dissolving process involves a consideration of the relative strength of three intermolecular attractive forces. The type of forces between solute-solute molecules and solvent-solvent molecules must be considered. These intermolecular attractions must be broken before new solute-solvent attractive forces can become effective. Perhaps the bond breaking and bond forming processes take place simultaneously.
