When does water form clouds?
When the air cools, its molecules come closer together. Thus, molecules of water vapor in the air come closer together, too. Then, the molecules of water vapor condense (or turn from gas to liquid state) on tiny solid particles in the atmosphere. The tiny droplets of water result from condensation form the clouds that we see in the sky.
Why air is transperent?
Air is transparent because the molecules it is composed of are so tiny and spread out. Air has a very low density unlike solid materials like rocks or dirt.
What separation process does masks that are worn by spray painters prevent tiny specks of paint entering the lungs but allow the air to get through?
The fibre of the mask traps dust and paint molecules. Air can get through, as air molecules are very much smaller, passing through the minute holes in the fibre.
Is water vapor mini molecules?
A single water molecule is too small to see. Water vapor is when the molecules begin to condense, several molecules forming together, forming tiny water droplets that are held aloft by the motion of the air around them.
How does smell travel through the air to reach our noses?
Smell travels through the air as tiny molecules released from objects or substances. These molecules move through the air and enter our noses when we breathe in, where they are detected by special cells in our nasal cavity that send signals to our brain, allowing us to perceive the smell.
The tiny air sacs in the lungs that take oxygen from the air and put it into the blood?
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Are molecules small?
yes , you can not see them because they are tiny. they are more tiny than dust
What is the mixture of air?
Air molecules and water molecules!
What is the adjective in this sentence - it waved its tiny hand in the air?
tiny
What does the word molecules?
Molecules are very tiny particles.It comes from the word which means "mass".
Which occurs when air is compressed A. Air Temp rises and air molecules move faster B. Air temp decreases C. Air temp decreases and air molecules move faster D. Air molecules move slower?
A. air temperature rises and air molecules move faster
Does a red balloon has more mass then green balloon?
Yes. Air is made up of tiny molecules and atoms (That can only be seen with the most powerfull microscope). The molecules and atoms are "matter". So air has matter anywhere it might be.
