answ2. Albert Einstein worked on the Brownian motion of (visible) dust particles in the air. This was one of his early investigations.
You should try and find this research, as it is an excellent example of a simple but profound experiment. try 'Brownian Motion' in your favourite search engine.
Yes, when you exhale in cold air, the moisture from your breath can condense into tiny water droplets, making it visible as a cloud of mist. This is because the cold air cannot hold as much moisture, causing it to condense and become visible.
Water molecules displace some of the air molecules, reducing the overall pressure within the air. This is because the water molecules take up space in the air, leading to a decrease in the number of air molecules per unit volume.
No, molecules in the air are not part of the hydrosphere. The hydrosphere refers to all the water on Earth - this includes oceans, lakes, rivers, and groundwater. Molecules in the air are part of the atmosphere, which is a separate component of the Earth's systems.
Air molecules attract odors through their ability to carry and transport odor molecules. When an object releases odor molecules into the air, these molecules travel through the air and interact with the receptors in your nose, enabling you to detect the smell. The interactions between the odor molecules and the receptors in your nose create the sensation of smell.
If air had a million molecules, approximately 400 out of a million molecules would be carbon dioxide. Carbon dioxide makes up about 0.04% of Earth's atmosphere.
Water becomes visible in large quantities when there are enough molecules to scatter and reflect light, typically in the form of droplets in the air (e.g., clouds, fog) or bodies of water (lakes, oceans). In smaller quantities, such as a glass of water or a stream, water molecules themselves are not visible to the naked eye.
Air consists of molecules that are spread out and not concentrated enough to reflect or scatter light in a way that makes them visible to the human eye. Additionally, the particles in the air are smaller than the wavelengths of visible light, which also contributes to their inability to be seen.
The wavelength of visible light is larger than molecules.
Air is made up of Oxygen, Nitrogen, Argon, Carbon dioxide, Methane which is (CH4), Xenon, Hydrogen, and Krypton. Since these molecules are not visible air is a homogeneous solution/
Clean air being colorless indicates that it does not absorb visible light in the same way colored substances do. This means that visible light can pass through air without being absorbed or scattered by its molecules.
Air molecules and water molecules!
Yes, air can condense when it cools. As air cools, its molecules lose energy and move closer together, which can lead to condensation of moisture in the air, such as forming clouds or mist. In extreme cases, air can also condense into visible water droplets or frost.
Wind is invisible because it is made up of moving air molecules that are transparent to the human eye. We can only see things that reflect or produce light, and air molecules do neither. Wind becomes visible when it carries objects like dust, leaves, or water droplets.

A. Air temperature rises and air molecules move faster
No, a vacuum by definition is a space with no air molecules present. Therefore, there are no air molecules inside a vacuum.
Water molecules displace some of the air molecules, reducing the overall pressure within the air. This is because the water molecules take up space in the air, leading to a decrease in the number of air molecules per unit volume.
