Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
When matter changes in shape size or type but remains with the same substance?
That is a physical change. The chemical composition of the substance does not change during a physical change, only its physical properties like size, shape, or state of matter.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Are changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.

How do the particles that make up matter compare during physical and chemical changes?
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.
What does not always stay the same and can undergo physical and or chemical changes?
Matter can undergo physical changes, such as changing state from solid to liquid, or chemical changes where new substances are formed. These changes alter the properties of the matter but do not change the fundamental makeup of the atoms and molecules involved.
What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
Is Matter always retains its original state?
No, matter can undergo physical or chemical changes that alter its original state. Physical changes, like melting or freezing, do not change the chemical composition of the matter, while chemical changes result in the formation of new substances with different properties.
When heat is absorbed is it a chemical change?
No. Rather released. As during the physical changes in the states of matter, there is breaking of bonds involved. Whenever bonds are broken, the atoms of that matter come closer and energy they give out is more as compared to energy taken while breaking bonds. Hence, Physical changes at the level of states of Matter are always Exothermic i.e. RELEASING HEAT.
Changes in properties of matter are called?
physical or chemical changes
Is freezing water a physical or chemical change?
Freezing (melting, boiling, condensing) are always phycal changes (of matter)
What is physical and changes in matter?
a physical is a change to a substance
A physical change occurs when matter changes state?
no physical change does not change matter
How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
What is the form or appearance of matter altered during a change?
During a change, the form or appearance of matter can be altered through physical or chemical processes. In physical changes, such as melting or dissolving, the substance retains its chemical identity but changes state or shape. In chemical changes, such as combustion or rusting, the matter transforms into new substances with different properties. These alterations can affect color, texture, state (solid, liquid, gas), and other physical characteristics.
