According to the kinetic-molecular theory the atoms of a gas have more energy than what other state of matter?
The atoms of a gas have more energy than the atoms in a liquid or solid state of matter. In a gas, the atoms are moving around freely and have higher kinetic energy compared to the more constrained motion of atoms in a liquid or solid.
What happens to the atom when a substance changes state from a liquid to a gas?
atoms gain more kinetic energy, so they are moving so rapidly that the intermolecular attractions can no longer hold them in liquid form.
On what principle do most thermometers work A when liquid absorbs heat it loses kinetic energy B as the temperature rises the molecules in liquid move more slowly C kinetic energy causes temperatur?
On what principle do most thermometers work? As the temperature of the liquid in the thermometer gets hotter, the molecules move faster. As the molecules move faster, they produce greater pressure. The only free surface is the top. This greater pressure causes the liquid to expand, causing the liquid to rise in the thermometer. A. When liquid absorbs heat it loses kinetic energy. Kinetic energy = ½ * mass * velocity^2 When a liquid absorbs heat, the molecules move faster. Kinetic energy is proportional to the square of velocity of the molecules. So, since the molecules are moving faster, the liquid gains KE. B As the temperature rises, the molecules in liquid move more slowly. Temperature is the measure of the average Kinetic energy of the molecules of a substance. Let's determine what causes the temperature to rise. Suppose you half fill a small metal can with 50º F water, and place it in a pan with 120ºF water in it. The molecules of the 120ºF water are moving very fast. They collide with the atoms in the outer surface of metal can, making these atoms vibrate faster. As these atoms vibrate faster, hitting the atoms in the inside of the metal can harder, the atoms inside vibrate faster. These atoms in the inside of the metal can hit the molecules of the 50º F water, making these water molecules move faster. Since the water molecules of the 50º F water are now moving faster (greater velocity), they have more kinetic energy. So, the temperature of the water in the can is getting warmer. It is a chain reaction. C kinetic energy causes temperature? Temperature measures the kinetic energy. Kinetic energy = ½ * mass * velocity^2 Kinetic energy measures the mass and velocity of atoms and molecules. When the atoms are moving faster the temperature is higher.
How does kinetic energy relate to the heating of water from a solid to a gas?
The motion of the atoms/molecules means they have kinetic energy. When you heat something, that is how the heat is stored. If the motion gets too big, the atoms/molecules no longer stick together and you get a liquid, ultimately a vapour or gas.
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 atoms in a liquid transfer heat to nearby atoms?
On a molecular scale, thermal energy is the kinetic energy of individual particles. In a liquid, this thermal energy is transferred to nearby atoms by collisions; a high-speed particle in the liquid collides with a lower-speed particle, transferring some kinetic energy from the high-speed particle to the low-speed particle. When this happens with a large number of particles, thermal energy transfer results.
What happens to the atoms of an object is thermal energy is increased?
When the thermal energy of an object is increased, the atoms within the object gain kinetic energy and vibrate more rapidly. This increased vibration causes the atoms to spread out and leads to the object expanding or changing state, such as from solid to liquid or liquid to gas.

The atoms of a gas have more energy than the atoms in a liquid or solid state of matter. In a gas, the atoms are moving around freely and have higher kinetic energy compared to the more constrained motion of atoms in a liquid or solid.
What happens to the atom when a substance changes state from a liquid to a gas?
atoms gain more kinetic energy, so they are moving so rapidly that the intermolecular attractions can no longer hold them in liquid form.
What causes liquid to freeze kinetic energy?
When a liquid is cooled, the kinetic energy of its particles decreases. At a certain temperature, the average kinetic energy becomes low enough for the particles to slow down and form a ordered structure, transitioning from a liquid to a solid state due to the attractive forces between them.
Do atoms have kinetic energy.?
Yes, atoms have kinetic energy as they are constantly in motion due to their thermal energy. This kinetic energy contributes to the overall temperature of the substance in which the atoms are located.
The average kinetic energy of the atoms that make up a substance which is changing from a liquid to a solid is .?
Heat of fusion.
How does an atom in a liquid transfer heat?
Heat does not exist at the level of atoms, at the level of the atom its kinetic energy; which is only observed as heat at the macroscopic/bulk level.Atoms with more kinetic energy bounce harder against other atoms, transferring more kinetic energy to those atoms. This has two effects at the macroscopic/bulk level, where heat is observed:direct transfer of kinetic energy results in diffusion of heat, called conductionkinetic energy pushes the atoms further apart causing a reduction in density, enabling a process called convectionif the liquid is accelerating or in a gravitational field
When the kinetic energy of atoms increases thermal energy increases or decreases?
Thermal energy (temperature) is the measurement of kinetic energy of atoms moving in a substance, therefore, as the speed (kinetic energy) of these atoms increases, thermal energy increases as well.
How does the temperature correspond to the kinetic energy of the atoms?
The temperature of a substance is directly related to the average kinetic energy of its atoms. As temperature increases, the atoms move faster and have higher kinetic energy.
Is Kinetic energy a solid liquid or gas?
Kinetic energy is the energy of motion. Heat is a form of kinetic energy (the movement of individual atoms or molecules) so the liquid phase contains more kinetic energy than the solid and the gas phase has more kinetic energy than the liquid phase. However, kinetic energy can also be imparted to a mass as a whole in which case if the total mass of the phases was constant the this imparted kinetic energy would be the same for all phases.
What kind of energy is the movement of atoms?
The energy that is present in the movements of an atom is kinetic energy, which is the energy of motion.
