the chemicals reacts faster
During a physical change, the composition of matter remains the same. The atoms and molecules of the substance do not change; only the arrangement or state of the matter is altered. This means that no new substances are formed during a physical change.

Physical change, as change in state.
A change of state does not affect an object's mass because mass remains constant regardless of the state of matter (solid, liquid, gas). The state change only impacts the arrangement and movement of the particles within the object, not the total amount of matter it contains.
No, a change of state does not affect the amount of matter in a sample of water. When water changes from solid to liquid (melting) or from liquid to gas (evaporation), the total mass remains constant, as mass is conserved during these transformations. The molecules of water simply rearrange themselves, but no matter is lost or gained in the process.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
physical
Temperature.
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
During phase changes the temperature of a substance does not change.
A change in state of matter, such as melting, freezing, or boiling, will affect the arrangement of particles without changing the chemical composition of the substance. For example, ice melting into water involves a change in state from solid to liquid, but the chemical makeup of water remains the same (H2O).
Yes there must be achange;but heat is required to change liquid state into gaseous state.
