What effect does cohesion produce where water and air meet?
Cohesion, or the attraction of water molecules to other molecules through intermolecular bonding, produces the effect of surface tension at the water/air boundary.
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
What is the process where air cools and expands?
Adiabatic cooling - it means air is cooling without the transfer of energy in the form of heat. First remember that temperature is a measure of how fast molecules are moving, whereas heat is a form of energy which has the ability to speed up molecules. So heat is related to temperature but it is not the same. That is, temperature is a measure of speed, heat is a quantity of energy. Now as air expands, air molecules move away from each other. Since air molecules are moving away from each other they do not collide as hard. If air molecules are not colliding as hard they will slow down. And since temperature is a measure of how fast molecules are moving, the temperature goes down too (it cools). In this case, molecules are slowing down simply because they are being banged into with less force, not because there is a transfer of heat energy, and so the process is adiabatic. Note: The reason there is no transfer of heat (actually there is some, but it is negligibly small) is because air is a terrible conductor of heat.
Why does the air temperature get warmer quicker than water?
Heat travels faster in water because the molecules are more tightly packed than the molecules in air, allowing more contact with ice and greater rate of heat transfer.
Why are softdrinks best served cold?
The acid is kept in when the molecules are further apart ( closer they are more heat they produce hence making it warm ) and there is no diffusion of the air and bubble molecules in the air.
How does heat make molecules move?
The heat energizes the molecules.The molecules of air will move here and there as they are free. Molecules of solids vibrate at there place.Due to heat the molecules get energized that is the main thing.
Can people see heat?
Not directly. Light is a by product of heat. So anything which produces light is a visible indication of heat. Heat can also produce a shimmering effect as it aggitates air molecules changing the airs density which is visible to human eyes.
Why does air temperature go up?
Molecules. Remember, the faster the molecules move, the more spread out they become, and the hotter it gets (i.e. why an ice cube turns to water and vice versa when put it contact with hot air.) However, when you talk about air temperature, it is simply a solar effect. The more sun the land gets, the more heat, because the molecules are moving faster and creating heat energy. Hope this helps.
How does a can crush when you heat up the air inside then let it cool?
You must mean a can that you can heat when open and seal air tight when you let it cool. When you heat it the air inside is heated and expands; so the molecules spread out (less molecules=less air). When the can is sealed and cooled, the molecules move together and that creates a vacuum relative to the outside air pressure, and that pressure crushes the can.
How does wind exist?
Wind exists because of two main forces: The rotation of the earth, and the heat and light from the sun. The rotation of the earth causes wind because the natural tendency of air molecules is to stay still. The earth essentially is moving, and the air is essentially staying where it is, creating the illusion that the air is moving. This is called "the Coriolis Effect". The Coriolis effect is what causes the constant unchanging winds used by sailing ships. The heat from the sun is responsible for almost all of earth's weather, except for those mentioned above. The sun's heat causes the air molecules to become excited, and lack of heat makes the molecules stand still. Excited molecules expand, and create High Pressure. Still molecules contract and create low pressure. When high pressure air moves in to fill in the slight vacuum created by low pressure air, it creates wind. In short HOT AIR = HIGH PRESSURE COLD AIR = LOW PRESSURE HIGH PRESSURE TRIES TO GET TO WHERE THERE IS LESS PRESSURE.

What things can effect air to rise?
Heat can cause air to rise :)
How does heat from a radiator transfer?
The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
What type of energy is caused by air molecules vibrating?
The type of energy caused by air molecules vibrating is called sound energy.
How does lifting by heat cause air to rise?
Heat speeds up molecules, this causes the particles to rise
