What else can I help you with?
When aluminium metal is burnt in air what does it form?
When aluminum metal is burnt in air, it forms aluminum oxide (Al2O3), a white powdery substance.
On beating a carpet why do the dust particles come out?
Because when you shake it the particles break free of the threads!
When air particles are further apart what do you have?
When air particles are further apart, you have low air density. This can result in lower air pressure.
What are two nongaseous particles in air?
Dust particles and pollen are two examples of nongaseous particles that can be found in the air.
Why do alpha particles travel shorter distance in air than beta particles?
Alpha particles are larger and heavier than beta particles, so they interact more readily with air molecules through collisions. This causes alpha particles to lose their energy more quickly and travel shorter distances in air compared to beta particles, which are smaller and lighter. Additionally, alpha particles have a higher ionization potential, leading to more interactions with air molecules and a shorter range in air.
Can you protect yourself from aluminum particles?
You cannot protect yourself fully from aluminum particles, since they can be found in the air we breathe.
What causes the visibility of particles in the air?
Particles in the air become visible when they reflect or scatter light. This can happen due to factors such as pollution, dust, smoke, or moisture in the air.
What happens to air particles as energy is released?
As energy is released, air particles gain kinetic energy and move faster, leading to an increase in temperature. This causes the air particles to expand, become less dense, and rise due to convection currents.
How far does beta travel in air?
Beta particles can travel a few feet in air, but they can be stopped by a thin sheet of aluminum or plastic. The distance beta particles travel depends on their energy, with higher energy particles traveling farther.
What will happen to the plants if the air is hazy and filled with dust particles?
They grow slower.
Solid particles and gases that are released into the air pollution today?
emissions
What will happen to the air particles in a sealed balloon if it is cooled?
Cooling the air inside a sealed balloon will cause the air particles to slow down and lose energy, resulting in a decrease in pressure. As a result, the balloon will shrink in size due to the decrease in pressure exerted by the air particles on the balloon walls.
How do air particles behave when under pressure?
When air particles are under pressure, they are pushed closer together, increasing their density. This results in an increase in the number of collisions between particles, creating higher pressure within the system. If the pressure is released, the particles will spread out to lower the density and pressure back to equilibrium.
What does air move from?
air moves from particles to particles
Is aluminum found in the sea or in the air?
Aluminum is found in lakes as well as the air. Aluminum is element that is in the boron group of chemical elements.
What happen to the air particles if there is a compression?
When air particles are compressed, they get pushed closer together, increasing their density and pressure. This results in the volume of the air being reduced while the temperature of the air typically increases due to the compression process.
What can alpha particles can pass through?
Alpha particles can pass through very few substances. It can travel in air but has a range of only a few centimetres.
