How can you magnetize water?
SeeMagnetic purification apparatusUnited States Patent 6103113As an example of how to purify water from a river by precipitating the impurities with a magnetic particle containing flocculant and then filtering passing the water through a magnetic field
What is the process of turning water into a vapor?
Vapor is one of the 3 usual states of matter. When the ave. kinetic energy of the molecules of a substance reach a certain point (different for all matter) the bonds holding the molecules together break apart. Such can occur when a substance is heated, for example. Those molecules that break away and leave the liquid state are regarded as vapor. If the substance is liquid water......the vapor is called water vapor.
What is Nuclear Magnetic Resonance?
let us take any substance in nuclear magnetic resonator.Let it be ethyl alcohol .Now an electro magnetic radiation having certain frequency is incident on the substance .As same energy is given to the substance all the hydrogen atoms get excited with same frequency[because same energy is given i.e (planck's constant x frequency) is constant].So because of same frequency, all hydrogen atoms are in resonance.Hence we can get an output. But all the peaks in the output should be same.Because of shielding and deshielding effects ,difference in curves can be observed Basically, with nmr, you align spin states along the magnetic field. You introduce a radiative pulse perpendicular to the magnetic field and record the interaction of the nuclei to this pulse. It is good for elucidating structures in organic chemistry
What type of force exists Between Molecules?
There are only four ways that substances interact, or if you prefer, four forces in the universe. They are gravity, the weak nuclear force, electro-magnetic, and the strong nuclear force. In molecules ( presumably in liquid or gaseous states ) they will be slightly pulled together by gravity, but it is the electro-magnetic force that governs everything else. Whether they bind together, break down into component atoms or simpler molecules, form new compunds, etc. is all part of the electro-magnetic interaction.
What is the number of molecules of 0.24 moles of oxygen?
The number of molecules in 0.24 moles of oxygen can be calculated using Avogadro's number, which states that there are 6.022 x 10^23 molecules in one mole of any substance. Therefore, there are approximately 1.45 x 10^23 molecules of oxygen in 0.24 moles.
Is a modern United States penny magnetic?
Neither the original copper or the newer version copper-zinc penny is magnetic. The 1943 steel penny was the only penny effected by a magnet.
What are the Auroras in the upper atmosphere caused by?
Aurora are caused by energetic particles that emanate from the Sun, these collide with molecules in the upper atmosphere. The collision pushes the molecules into higher energy states and when the molecules fall back to lower states they emit photons.The Earth's magnetic field accelerates the solar particles and therefor the aurora are seen in a ring centered around the north and south magnetic poles.
How heat energy can change the states of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
What happens if you suspend a bar magnet so it can go freely?
if the magnet has a low enough mass, and the string induces very little forces and friction on the magnet, it will act like a compass, the south end will point to the north pole and vice versus with north

What is directional properties of a magnet?
The directive property of magnetism states that when a magnet is suspended in air, it's N and S (north and south) axis's will remain in the same direction as the earths magnetic meridian. I.e. It will continuously point north and south. If you were to mark one side red and one side blue and spin the magnetic 6 times it would still resort back to the original direction it was in.
Why do magnetic poles always occur in pairs?
Because, as Newtons third law states, "To every action there is an equal and opposite reaction."
How is the thermal energy of a substance related to its state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.

A physical change in a substance?
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
