What happens to speed of the particles if the size of the object gets bigger?
it blows up and down, up and down
When an object increases in temperature do the particles speed up or slow down?
They speed up. Heat is actually molecular motion. Absolute zero (−459.67°F) is the temperature where the particles have no motion at all.
What is the definition of velocity lag?
In a flow of matter, such as in a rocket, velocity lag is the speed difference between the flowing gas particles and solid/liquid particles. Any amount of velocity lag slows down the overall force and speed of the matter flow.
When the unstable nuclei of heavy atoms radioactively decay they eject high speed particles this causes materials containing radioactive elements to a. increase in speed b become hotter c. cool down?
The energetic particles (either electrons, neutrons, or helium nuclei containing two protons and two neutrons) are absorbed by other nearby atoms. This may cause those atoms to break down and radiate other particles. Then eventual end result is always heat.
Why do material particles vibrate?
Thermal energy in a material causes the particles to vibrate. Particles cannot stop moving altogether, since they would then violate the Heisenberg uncertainty principle. This states that we cannot know a particles speed and position to infinite precision at the same time. A particle in a material that is not jiggling would violate this. The more and faster that the particles are jiggling, the more energy they must have. If they come into contact with particles that are jiggling less, then that energy spreads. The faster jiggling particles slow down, transferring their energy to the slower particles, which speed up. This is just the transfer of heat from one material to another! Here's a good video from famous physicist Richard Feynman explaining "jiggling atoms."
Does sublimation particles slow down or speed up?
During sublimation, particles will speed up. Sublimation is the transition of a substance to go from a solid to a gas without going through the liquid phase.
What happens during condensation and sublimation?
Particles increase their motion because of increased kinetic energy on the molecular level. This breaks bonds holding them together as a solid and the particles become gases during sublimation. During condensation the opposite occurs. Particles are losing heat energy which means a loss of kinetic energy slowing the particles down to the point that the attractive forces form bonds causing the gas to become a liquid.
A liquid cools down and changes to solid what happens to the speed of particles?
The average speed of the particles decreases.
Do gas particles speed up or slow down when heated?
They speed up.
Will particles slow down if you add heat to them?
No. Actually they would speed up.
What happens to speed of the particles if the size of the object gets bigger?
it blows up and down, up and down
What happens to the speed of particles when freezing occurs?
When molecules freeze the rate of speed they go at tends to slow down
When an object increases in temperature do the particles speed up or slow down?
They speed up. Heat is actually molecular motion. Absolute zero (−459.67°F) is the temperature where the particles have no motion at all.
What effect does the speed of molecules have of matter?
The speed of the particles in a substance changes when the temperature changes. Heating the substance causes the particles to speed up, while cooling causes the particles to slow down.
How does a grass waterway affect the speed of the water?
A grassed waterway slows down the speed of running water and does not let the water pick up soil particles.
Which type of saw flux is susceptible to breaking down into fine particles during circulation?
agglomerate
What is the definition of velocity lag?
In a flow of matter, such as in a rocket, velocity lag is the speed difference between the flowing gas particles and solid/liquid particles. Any amount of velocity lag slows down the overall force and speed of the matter flow.
