Is it true that particles can only evaporate from a liquid at temperatures above liquids boiling point?
It is not true; evaporation occur at the surface of a liquid and the temperature is under the boiling point.
How do magnets get poles?
Magnetism of a substance depends on the movements of the surface electrons. We know that when a charged particle moves in a direction it generates a field in the perpendicular to the direction of motion. this field has the tendency to attract iron particles and thus called a magnetic field. All metals have free surface electrons but only some has the tnedency to magnetise easily. Read about diamagnetism, paramagnetism and ferromagnetism.
What is the change of state is evaporation?
Evaporation is the physical change of state of a liquid to a gas (or vapour). It is the loss of particles at the surface only, and these particles remove the kinetic energy of the fluid which causes cooling e.g. sweating. The reverse is condensation.
Why is magma only made keep underground?
After magma reaches the surface it is no longer magma it is called lava.
Can you fill in the blank to total energy of a materials particles causes particles to vibrate in place?
All states of matter have vibrating particles, but solids' particles vibrate only.
What is it called when particles only leave the surface of a liquid?
This phenomenon is called evaporation.
The particles in a surface water wave move back-and-forth only?
the particles in a surface water move back- and- forth only.
The particles in surface water wave move back and forth only?
the particles in a surface water move back- and- forth only.
Why evaporation is called a surface phenomenon?
Evaporation can only take place on the surface of liquids because that is where the molecules with the highest kinetic are found. Only molecules with high kinetic energy are free to escape into the atmosphere.
When water is boiling only particles of the surface of a liquid can turn into gas?
Yes
Can particles of a solid solute can escape into the solvent only at the surface of the solute?
Yes
What is the vaporization at the surface of a liquid called?
Evaporation. It only happens at the surface of a liquid.
Why subatomic particles are called fendamental particles?
Not all of them are; the only direct subatomic part of the atom that is fundamental is the electron (which is a type of lepton.) Only particles made up of no smaller parts are called fundamental particles. For example, the proton (just like the neutron, except with a small difference) is not a fundamental particle because it is made of quarks, which are fundamental particles.
Only when is transfered is it called heat?
Yep. Only when the fast moving particles are transferring in Conduction,Convection and Radiation is it called "Heat".
What prevents electrically charged particles coming from space space from reaching the earth's surface?
The Earth's magnetic field, although it does not deflect all charged particles; it only deflects most of them.
Why do water spiders float?
there is a thing called surface tension. Surface tention is the uneven forces acting on the particles on a surface of a liquid and this causes the water to act like a sort of thin film and therefor the spider can float.
Liquid changing to a gas only at the surface is called?
vaporization
