What happens to the mass when a physical change happens?
During a physical change, such as melting or boiling, the mass remains constant. The atoms and molecules rearrange themselves, but none are added or lost, so the total mass remains unchanged.
What type of property is a change of state?
Change of state of a substance is a physical property!
Which equation represents a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
What happens to energy during a change of state Why is it physical change?
During a change of state, energy is either absorbed or released as heat. This is because the particles in a substance need energy to break their bonds and move into a new arrangement. A change of state is a physical change because it does not involve a change in the chemical composition of the substance, only its physical properties.
What is mechanical change?
Mechanical change refers to changes in physical properties or characteristics resulting from forces or interactions in a system. This can include changes in shape, size, position, or motion of objects due to external forces or energy inputs.
What happens to the characteristic properties of a substance when a physical change occurs?
i dont know you tell me
What is pressure in physical change?
Pressure is not a change, it is a characteristic.
Is insoluble a chemical or physical characteristic?
Dissolution is physical change.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
Is luster a physical or chemical change?
Luster is not a change, it is a characteristic.
Is the melting point of silver a physical or a chemical property?
The change in the state of matter between solid, liquid and gas are not chemical changes. The melting point of a substance, silver in this case, is a physical characteristic.
What kind of change happens when a brick crumbles Physical or chemical?
It is a physical change.
What happens in a chemical change but not in a physical?
Molecules permanently change. In a physical change the effects are reversible.
What is a characteristic of of matter that is exhibited without a change in identity?
Physical property
What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
Is rough texture physical or chemical property?
Coarseness is a characteristic, not a change.
Is inflammability physical or chemical change?
Inflammability describes a chemical property (a chemical change).
