When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
Even if you change the shape and amount of a substance it's stays the same?
This statement is incorrect. Changing the shape or amount of a substance can alter its physical and chemical properties. For example, breaking a substance into smaller pieces can increase its surface area and affect its reactivity, while changing the amount of a substance can change its concentration and impact its behavior in a reaction.
What are four things that indicate that a chemical change may have taken place?
Change in color: If the substance changes color during a reaction, it may indicate a chemical change. Formation of gas: Production of gas bubbles, fizzing, or bubbling is a sign of a chemical change. Temperature change: Significant heat or cooling effects can indicate a chemical reaction is occurring. Formation of a precipitate: When a solid substance forms in a solution, it suggests a chemical change has taken place.
What takes place during a chemical change?
During a chemical change, the identity and composition of a substance are altered as new chemical bonds are formed or broken. This change is usually irreversible and produces a new substance with different chemical properties compared to the original materials. Examples include combustion, oxidation, and digestion.
What Change occurs when One substances reacts with another substance?
When one substance reacts with another, a chemical change takes place. This involves the breaking and forming of chemical bonds, resulting in the creation of new substances with different chemical properties than the original ones.
What take place when a substance undergoes a chemical change?
an explosion (fact)
What is the definition chemical change?
Chemical ChangesAs opposed to a physical change, chemical changes are present when the substance undergoes a chemical reaction and produces a new substance. A chemical change is a chemical reaction that will always take place for there to be a chemical change. Signs that a reaction is taking place: Formation of gases (bubbles), Color change, production of heat or light, and the formation of a solid. a change in composition and characteristics of matter.new substance maybe formed.original substance and form may be lost.new color and shapeExamplesFermentationPhotosynthesisRusting nailSpoiling milkDigesting food
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
When a chemical change is in place does no new substance form?
No, a new substance is normally formed
When a change makes a new substance you say a - has taken place?
A chemical reaction makes a new substance.
How does matter chemically change?
The chemical changes take place on moleculer space. A chemical change form (or) produce a new substance.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place explain?
When sugar is heated for a short time, it undergoes a physical change called caramelization. During this process, the sugar molecules break down and recombine into a new substance without changing the chemical composition of the sugar molecules. The result is the formation of a thick, colorless liquid substance known as caramel.
What does a substance changed into when chemical change take place?
The reactants are changed in products having new chemical composition.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
Even if you change the shape and amount of a substance it's stays the same?
This statement is incorrect. Changing the shape or amount of a substance can alter its physical and chemical properties. For example, breaking a substance into smaller pieces can increase its surface area and affect its reactivity, while changing the amount of a substance can change its concentration and impact its behavior in a reaction.
