The thermal energy of an object is created by the?
Movement of particles
What happens to the particles when matter gets hotter?
The particles move faster. Thermal energy is a measure of kinetic energy of molecules.
What happens when heat energy is taken away fron molecules?
As the heat is removed, the kinetic energy of the particles decreases and they start moving very slowly. Quick reminder: kinetic energy is the energy associated with a particle's motion. The faster a particle moves, the larger its kinetic energy is.When enough energy has been removed from the system and the particles are in super slow motion, bonds begin to form between the molecules. These bonds act like glue and freeze the molecules into place.
Do Particles in a solid have less kinetic energy than particles in a liquid or gas?
Kinetic energy is the energy of motion. Atoms or molecules of a solid are tightly constricted and can really only vibrate a little, so they have very littel kinetic energy. Liquids can flow, so those atoms/molecules have a little kinetic energy, and the molecules with the most kiinetic energy are those in gases.
How do forces between particles liquids compare to forces in the other states of matter?
the intermolecular forces/van der waals forces operate on an intermolecular scale giving you the 3 states of matter when these molecules are at different energy levels
The thermal energy of an object is created by the?
Movement of particles
What happens to particles at the molecular level when water freezes?
The particles' movements slow down. Particles (or atoms) contain energy; the more energy the particles have, the more the particles move. However, there is a certain level of energy at which the bonds between the particles break; this energy is called bond energy. For example, take a boiling pot of water. At the atomic level view, heat is equal to energy; the heat is transferred from the flame to the H2O molecules, giving them more energy and making them move faster. The the H2O molecules break apart, turning to hydrogen and oxygen gas. In an ice cube, the heat/energy is taken from the H2O molecules, slowing them down and creating a packed solid.
What is particle energy?
It is the energy that affects motion of particles, which are atoms and molecules.
What happens to the particles when matter gets hotter?
The particles move faster. Thermal energy is a measure of kinetic energy of molecules.
Kinetic energy of particles?
The SI unit for kinetic energy is joule (J).
Temperature is a measure of the average kinetic energy of what?
Of particles, such as atoms or molecules.
Particles in a liquid have less energy than particles in a. water b. a computer c. ice d. a gas?
In terms of kinectic energy molecules in soilid will have least energy. Molecules in lquid have less energy than in gases. Molecules in gaseous state have maximum energy. Entropy of a substance increases from solid to liquid to gas.
What happens to the particles in a object as it cools?
The vibrational energy of the atoms and molecules reduces.
What is the diffusion of particles without the use of energy?
Osmosis is an example of movement of particles from an area without the need of additional energy. If a state is not in equilibrium particles can move from one area to another without additional energy.
How do the particles of water evaporate in an open container?
When the kinetic energy of water molecules is sufficient some molecules can escape in the atmosphere.
What is a measure of the average motion of the molecules in a substance?
When we heat a substance, the energy absorbed is converted into kinetic energy of the particles in it. The faster the particles in it vibrate, move, collide, etc. the higher the temperatureof a substance.So the expected answer is Temperature
What happens to particles in soundproofing?
The effect of soundproofing -- any means of reducing the sound pressure with respect to a given sound source and receptor -- on particles depends on the state of the particles. Soundproofing reflects or absorbs the energy of sound waves that transforms into vibrational energy, thus reduces the vibration and its resultant effects. For particles in the gaseous state, reduced vibration from soundproofing decreases the energy transferred to the free, widely-spaced gas molecules, thus lessening the resultant fluctuation in motion of the gas molecules. As for particles in the liquid and solid state, reduced vibration from soundproofing has a different effect on the particles. In liquids, energy of vibration transferred to the molecules are mostly absorbed by the intermolecular interactions and bonds (e.g., hydrogen bonding between water molecules). In solids, energy of vibration transferred to the molecules are absorbed by the chemical bonds between the particles of the solid. Thus, for both liquids and solids, soundproofing reduces the amount of energy absorbed by the particles.
