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 an apple turning brown physical change?
It is both physical and chemical change as it changes its appearance , and it results in a new substance also
What is energy that results from chemical changes is?
well what had happen was..... it makes generate heat, electrical, mechanical, and sound energies
All of the following are examples of chemical change except?
All of the following are examples of chemical change except physical changes such as melting, freezing, or dissolving. In a chemical change, the substances involved undergo a transformation that results in new chemical properties, while in a physical change, the substance remains the same at the molecular level. Examples of chemical changes include rusting, burning, and digestion.
Is the rotten cabbage is chemical or physical changes Why?
The rotting of cabbage is primarily a chemical change. This process involves the breakdown of organic compounds by microorganisms, leading to the production of new substances, such as gases and acids, which contribute to the odor and appearance of decay. Unlike physical changes, which do not alter the chemical composition of a substance, the decomposition of cabbage results in a transformation of its chemical structure.
What is a description of chemical changes?
Chemical change is any change that results in the formation of new chemical substances.
Is leaves produce oxygen a physical or a chemical change?
Its a chemical change. Leaves breathe in carbon dioxide. They use it to carry out the process of photosynthesis that is preparation of food for growth. Chemical changes involving salts, water, carbon dioxide take place in the presence of sunlight that results in the liberation of oxygen into the atmosphere. At night however in the absence of sunlight it breathes in oxygen to prepare food, since photosynthesis is not possible due to absence of sunlight.
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.
What is the formation of soil a result of?
Soil formation results from chemical changes, abrasion, and erosion, to simplify the process.
What results after a chemical change?
A chemical change produces a form of matter that was not there before. Evidence of a chemical change could be changes in temperature, color, smell, and the production of a gas or a precipitate.
Is an apple turning brown physical change?
It is both physical and chemical change as it changes its appearance , and it results in a new substance also
What launch angle of a projectile, in the absence of air resistance, results in the longest range?
The launch angle that results in the longest range for a projectile, in the absence of air resistance, is 45 degrees.
What is the most important quiestion to ask to determine whether a change is physical or chemical?
The most important question to ask is whether the change results in a new substance being formed. Physical changes involve a change in appearance, state, or size of a substance without forming a new substance. Chemical changes involve a reaction that results in the formation of new substances with different chemical properties.
In a battery chemical energy changes to?
In a battery, chemical energy is converted into electrical energy. This process involves a chemical reaction within the battery that results in the flow of electrons, creating an electric current that can be used to power devices.
Why do we say that chemical reactions always involve changes in energy?
Chemical reactions involve the breaking and forming of chemical bonds, which requires energy to overcome or release. This results in changes in the potential energy of the system. Additionally, the activation energy required to start a chemical reaction is a clear demonstration of energy change.
What happens when S is heated in the absence of air?
When S (sulfur) is heated in the absence of air, it undergoes sublimation, meaning it changes directly from a solid to a gas without passing through a liquid state. This process results in the formation of a colorless gas with a characteristic odor of sulfur dioxide.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
