If you rub a magnet over a metal screw driver, you can magnetize the screw driver. This is because the magnet
ikadub [295]

The magnet can cause the alignment of electron domains in the metal screw driver on rubbing, causing magnetism.

The magnetism in a permanent magnet is produced by magnetic moments of electrons in the magnet's constituent material. The material's atoms are each like tiny magnet bars. As a result of the quantum mechanical effect, the majority of these tiny magnets now prefer to align in a single direction to form domains, consequently magnetizing the entire substance.

Electrons exist in magnetic metals as well, although they are arranged differently. A strong magnet has a magnetic field strong enough to cause residual magnetism in the metal screwdriver by aligning the domains in it on rubbing with the metal.

Avogadro's law states that the _____ of a gas is directly proportional to the _____ of the gas when _____ stay the same
attashe74 [19]

Answer:

The three blanks for this answer, are

1. volumen

2. moles

3. Temperature and pressure.

So, Avogadro's law states that the volume of a gas is directly proportional to the moles of the gas when temperature and pressure stay the same

Explanation:

Imagine you have 10 moles of a gas which is contained in 50 L. How many moles of that gas, you will have if the volumen has been reduced to 10 L. (Of course, don't forget that T° and pressure are the same)

There is an equation like this, initial moles /initial volume = moles at the end/volume at the end, (Avogadro law for gases), so 10/50 =moles at the end/10.  When u operate, moles at the end = (10 x 10) / 50.

Moles at the end are 2. Did u get it?. Volumen has been reduced, also the moles.

What is one way to decrease carbon?
katrin2010 [14]

Answer:

Buy local and eat a more diversified diet including less meat and dairy to reduce your carbon emissions resulting from the use of fossil fuel-based fertilizers, pesticides, and gas required to produce and transport of the food you eat. Support clean energy sources.

Explanation:  or

Alternatives to drivingWhen possible, walk or ride your bike in order to avoid carbon emissions completely. Carpooling and public transportation drastically reduce CO2 emissions by spreading them out over many riders.
