What happens to the movement of particles in an object when they are heated?
i dont know but all i know is that it is really hard lol
Positively charged particles that are found outside the nucleus of an atom?
The electron is the negatively charged particle found in the orbitals surrounding the nucleus in conventional matter.The muon is a negatively charged particle that can be produced in particle accelerators and can substitute for electrons in the orbitals surrounding the nucleus in muonic matter. In this case the orbitals shrink in diameter so much that the nuclei can occasionally touch at room temperature and pressure (which is not possible with electrons in those orbitals)!
What form of nuclear radiation gives off either particles emery that have no mass and no charge?
X-Ray and Gamma are photons. Photons have no mass and no charge. Well, sort of... Photons have no mass at rest state. Problem is, they don't sit at rest state. They move at the speed of light. At that speed there is an infinite mass multiplication effect from the Lorentz transformation, 1 / (1 - (1 - v2/c2)-1/2). Take a particle with no mass and multiply that mass by infinity and you get - well, officially, its indeterminate - unless you start talking about limits - then you get some mass. Bottom line - there is no particle with no mass, unless you happen to also be moving at the speed of light relative to the particle, and that would require infinite energy.
How do you explain melting using the particle theory?
the particle theory states that all matter in the world or universe is made up of particles. so the answers to your question is that when an object melts that particles in that object will start to move more rapidly, having more collisions and therefor the object will expands......... hope that helps
What makes acid?
an acid is anything with a PH level of 7 and lower, anything from 7 to 14 is defined as a base! As the number goes lower that means that the substance is more acidic. for example if you have a substance that has a PH of 6 and a substance that has a PH of 3. the one with the PH of three is alot more acidic than the one with a PH of six. an acid can also be defined as a substance which donates Hydrogen ions in a chemical reation. they can usually be identified as they will start with a 'H' ie. HCl or HF (hydrochloric acid and hydrofluric acids, respectivly).
What increases amount of solute in contact with solvent?
Smaller particle size for a start
What particle is used to start a nuclear fission reacion?
it might me neutron or atom idk but if u know then improve it thank you ~_~
How is energy passed from particle to particle during heat conduction?
As a particle absorbs the energy (heat) it begins to move and vibrate faster. This increased vibration and movement causes it to bump into surrounding particles more, passing the energy onto them. As more particles get bumped, more particles start to move in turn bumping their neighbors and conducting the energy or heat through the substance.
What a particle model motion diagram for an airplane taking off from an airport?
C) The dots would be close together to start with, and get farther apart as the plane accelerated.
Is neutron particle is required both to start and as a product in a fissin reaction?
Yes. That's how the reaction is self-sustaining: The product of one reaction is the reactant for the next.
What happens to the movement of particles in an object when they are heated?
i dont know but all i know is that it is really hard lol
What is a spark?
A spark is a small part of a burning substance thrown off by a fire. Sparks can also be generated by friction to start a fire.
What is heisenberg uncertainty principle and its importance in quantum mechanics?
The Heisenberg uncertainty principle is that the more you know about the speed of a particle the less you know about it's speed, and vice versa. This is because the more specifically you know where a particle is, the larger area there is in which there is a reasonable chance of finding a particle in within a time boundary, due to the interference effect. The reason the more you know about speed the less you know about position is a little more complicated. It is important for a number of reasons. For a start, there is another expression of the theory allows you to know bits and bobs about the particle. The other thing is that it is revealing about the nature of the way particles spread out, and is important in some equations and calculations
How does a catalyst increase the rate of a chemical reation?
A catalyst decreases the threshold energy value with which two particles must collide in order to react.
Who proposed the particle theory of matter?
The concept of an atom was first proposed by Democritus in the 5th century BCE. But he was ignored until the start of the 19th century that an English chemist named John Dalton again proposed it.
What happen to the particles of a liquid as it vaporizes?
The liquid particles gain energy (usually from thermal energy, i.e. heat) and start to get "excited." This means they vibrate and eventually break away from the surface of the liquid and into the surrounding gas. This particle of matter is still present, but not in liquid form.
When you rub two sticks together what force makes a spark?
Friction! When you rub objects or substances together the microscopic rough particle begins to heat up and eventually it gets hot enough to start the combustion process.
