A change in temperature leads to a change in the kinetic energy of the atoms in the particle.
electrons
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
No, thermal expansion is a physical change, not a chemical change. It occurs when a material expands or contracts in response to changes in temperature, without any change in the chemical composition of the material.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.

How does particle behavior change as an object changes from a solid to liquid to gas
Its length, linear density, thickness, and temperature all change.
Change of state of a substance is a physical property!
The particle in an atom that cannot change is the number of protons. If that changes, it is no longer the same element.
Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
An extensive property is a property that changes when the size of the sample changes, weight would change.
It is a physical property because the element/compound will change without involving a change in chemical composition.Physical
The particle model of matter describes matter as being made up of tiny particles (atoms and molecules) that are in constant motion. Changes in temperature or pressure affect the motion of these particles. With an increase in temperature, the particles move faster, leading to a change in state (e.g., solid to liquid to gas). Changes in pressure can also affect the arrangement and movement of particles, causing changes in state.
The temperature changes as the weather changes and the Earth tilts on its axis, causing the seasons to change.
It changes in proportion to the temperature change.
Change in temperature directly indicates a change in the mean amount of kinetic energy possessed by each particle. It also indirectly indicates a possible change in state, and a possible change in chemical properties too (chemical reactions often involve energy transfer in the form of temperature change).
