What else can I help you with?
What mixtures scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
These mixtures are colloids or very fine suspensions.
What is the composition of dust, and are atoms the building blocks that make up dust particles?
Dust is made up of a variety of particles, including dead skin cells, dirt, pollen, and other small debris. Atoms are indeed the building blocks that make up these dust particles, as everything in the universe is ultimately composed of atoms.
What is another word for granules?
Dust, particles, fragments, flakes, grime...
What are most dust particles in your house made of?
Most dust particles in your house are made of a combination of dead skin cells, pet dander, pollen, and other small particles like dirt and debris.
What is the type of erractic motion seen in dust particles suspended in water?
The erratic motion seen in dust particles suspended in water is called Brownian motion. This motion is caused by the random collision of water molecules with the dust particles, leading to their continuous and irregular movement.
Why do you see tiny shining particles in the beam of sunlight in a dark room?
Those mysterious sparkles are dust particles in the air.
When a ray of sunlight enters a dark room its straight path become visible because of dust particles hanging in the air?
Yes, when sunlight enters a dark room, it illuminates the dust particles in the air, making their path visible. The light scatters off the dust particles, creating a visible beam that shows the straight path traveled by the light.
What can cause a change in climate due to dust particles?
Dust particles can cause a change in climate by interacting with sunlight and affecting the Earth's energy balance. When dust particles are in the atmosphere, they can scatter sunlight back to space, leading to a cooling effect. However, if dust settles on snow or ice, it can decrease their albedo, leading to heating through increased absorption of sunlight.
Does sunlight cause dust to accumulate?
Sunlight does not directly cause dust to accumulate. Dust is mainly made up of particles like skin cells, pollen, and dirt that settle on surfaces over time. Sunlight can highlight dust particles, making them more visible, but it does not cause them to accumulate.
When ray of sunlight entres a dark room its straight path become visible because of dust particles?
Yes, when sunlight enters a dark room, its path becomes visible due to the dust particles in the air reflecting and scattering the light. This phenomenon is known as the Tyndall effect. The dust particles act as tiny mirrors that make the light rays visible as they pass through the room.
Why do dust particles in a bean of sunlight appear to sparkle?
Because the sunlight is reflecting off them at different points.
Why can you see a path of light in a sunbeam?
You can see a path of light in a sunbeam when there are particles in the air, like dust or pollen, that scatter the sunlight. This scattering causes the light to become visible and creates the beam that you can see.
What mixtures scatter a beam of light that passes through them-a phenomenon called the Tyndall effect?
These mixtures are colloids or very fine suspensions.
What happens when a comets dust particles enter our atmosphere?
When a comet's dust particles enter our atmosphere, they create bright streaks of light known as meteors or shooting stars. Friction with the atmosphere heats up the particles, causing them to vaporize and produce a glowing trail as they streak across the sky.
Why does sunlight attract dust?
Sunlight can attract dust particles because air currents created by temperature differences near a window or light source can cause dust to become more visible as it reflects the sunlight. Additionally, the warmth from sunlight can create convection currents that move dust particles around, making them more noticeable in illuminated areas.
Can sunlight cause dust?
Dust is made up of particles of all sorts of things. In places where people live, a great deal of dust comes from flakes of dead skin, which are being shed all the time. Dust mites, tiny microscopic creatures that feed on this dead skin, make up dust, too (including their waste and tiny skeletons). Particles of the environment contribute to dust as well: grit from the sidewalk, salt from the sea, dry earth, pollen from plants, smoke from burning materials. And Earth gets 10 tons of dust from outer space everyday, from the millions of meteors that burn up as they enter our atmosphere.
In bright sunlight dust particles in the air appear to dart about What causes this effect?
This effect is caused by the sunlight illuminating the dust particles in the air, making them visible. The movement you perceive is likely due to air currents or thermal convection currents that cause the dust particles to move around. The interaction between light, air currents, and dust particles creates the appearance of darting movement.
