How can you make something negatively charged?
To make something negatively charged, you can add extra electrons to the object. Electrons have a negative charge, so adding more of them to an object will give it a net negative charge.
What happens when scientists add heat energy to an object or take heat energy away from an object?
When scientists add heat energy to an object, the particles in the object gain kinetic energy, causing them to move faster and increasing the object's temperature. When heat energy is taken away from an object, the particles lose kinetic energy, moving slower, and decreasing the object's temperature.
Do you add or subtract if forces are acting on an object in the same direction?
add
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
What happens when you add alum to water?
crystals form
Why must a positively charged body have a deficiency of protons?
It doesn't. A positively charged body is deficient in electrons. In an uncharged object there are equal numbers of positively charged protons and negatively charged electrons. Removing electrons will leave more protons than electrons, so the object will be positively charged. Such an object is said to have a deficiency or electrons rather than a surplus of electrons because it is generally easier to remove electrons than it is to add protons. Electrons occupy the outer shells of an atom and have a much lower mass than protons. The protons, by contrast, are bound together in the dense nucleus.
Can a electrically-charge object attract uncharged object?
Yes, and in fact they do. You can easily see this yourself by rubbing a balloon on a sweater and then "sticking" it to a wall.This happens because of something called "induced dipoles".Let's say you have an electrically charged object ... negatively charged, for example.If you bring it near an uncharged object, what happens is that the electrons in the molecules of the uncharged object tend to be repelled by the charged object. They move as far to the opposite side as they can get.Because the electromagnetic force gets smaller with distance, the uncharged molecules now have a slight net attraction to the charged object, since the part of the molecule that's attracted to the charged object is now closer to the charged object than the part of the molecule that's repelled by it. This means the attractive force is very slightly greater than the repulsive force. For any individual molecule, it's not much, but there are a LOT of molecules in any object large enough to see, and those tiny attractions add up.
What happens to an object to make it positively charged?
An object becomes positively charged when it loses electrons. This can happen through processes such as friction, where electrons are transferred from one object to another, leaving one object with a positive charge.
What happens when you add an object in boiling water?
This object become warmer, or react with water, or is dissolved.
What happens to the volume if you add more of the object?
it turns up loud and you get in trouble
How can you make something negatively charged?
To make something negatively charged, you can add extra electrons to the object. Electrons have a negative charge, so adding more of them to an object will give it a net negative charge.
If you add pressure to an object what happens to its density?
the density will increase because there will be less space
What happens to an objects density if you add more of the substance to it?
If you add more of the same substance to an object, the density of the object will increase. Density is calculated by dividing the mass of an object by its volume, so as you add more substance, the mass increases but the volume does not increase proportionally, resulting in a higher density.
What happens when scientists add heat energy to an object or take heat energy away from an object?
When scientists add heat energy to an object, the particles in the object gain kinetic energy, causing them to move faster and increasing the object's temperature. When heat energy is taken away from an object, the particles lose kinetic energy, moving slower, and decreasing the object's temperature.
How do you know that nickel has a plus two charge?
because it will have more electrons add electrons= add charge
What happens when you add friction to an object in motion?
When you add friction to an object in motion, it opposes the direction of motion and generates heat as the object slides or rolls. This heat energy comes from the initial kinetic energy of the moving object and causes a loss in speed over time. Ultimately, the object will come to a stop due to the frictional force acting against its motion.
How a body can be charged?
A body can become charged either by gaining or losing electrons. When electrons are transferred between objects, one object becomes positively charged (losing electrons) and the other becomes negatively charged (gaining electrons). This charge separation creates an electric field around the objects.
