What else can I help you with?
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.
Is freezing point a physical property or physical change?
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.
Does pressure affect changes of state?
Yes, pressure can affect changes of states in matter. Increasing pressure can help compress gases into liquids or solids, while decreasing pressure can cause liquids to evaporate or solids to sublimate directly into gas.
Which physical property of water changes when it reaches melting point?
The transition from solid to liquid is a state change. Its ability to flow changes.
Is melting a change to metal physical changes?
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
Can an object undergo both physical and chemical changes?
Yes, an object can undergo both physical and chemical changes. Physical changes involve changes in physical properties like shape, size, or state of matter without altering the composition. Chemical changes involve a transformation at the molecular level, resulting in the formation of new substances.
What are the changes do materials undergo in physical change?
In a physical change, materials undergo a change in their physical state or appearance without changing their chemical composition. This can include changes in shape, size, phase (solid, liquid, gas), or state (melting, freezing, evaporating). Physical changes are usually reversible.
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.
Can matter undergo changes in both its physical and its chemical properties?
Yes, matter can undergo changes in both its physical and chemical properties. Physical properties changes do not alter the composition of the substance, such as changing state from solid to liquid. Chemical properties changes involve a chemical reaction that results in the formation of new substances with different chemical compositions.
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.
A physical change occurs when what?
A physical change occurs when a substance changes its physical form or state without changing its chemical composition. Examples include changes in size, shape, or state of matter (solid, liquid, gas).
List of solids which changes its state when heated?
Ice (solid water) changes to liquid water when heated. Wax solid changes to liquid wax when heated. Metal becomes molten when heated to its melting point. Paraffin wax solid changes to liquid paraffin wax when heated.
Are state changes chemical or physical changes?
Physical Changes
Why are change of state physical changes?
The identity of the property does not change so the physical properties change but not the chemical
Can matter undergo changes in both its physical and its chemical properties Explain please?
Yes, matter can undergo changes in both its physical and chemical properties. Physical changes involve alterations in the form or state of matter without changing its chemical composition, such as melting ice into water. Chemical changes, on the other hand, involve transformations at the molecular level, resulting in the formation of new substances with different chemical properties, such as rusting of iron.
Can all substances go through physical changes?
Yes, all substances can undergo physical changes. Physical changes do not alter the chemical composition of a substance, but rather change its physical properties such as shape, size, or state (solid, liquid, gas). Examples of physical changes include melting, freezing, boiling, or dissolving.
Which physical state of matter is the densest?
Solids are the most dense state of matter
