Is bouncing a ball a chemical change?
yes No. Nothing changes in its chemical nature.
Why is boiling water a physical change?
Boiling water is a physical change because it doesn't change the chemical composition of the water molecules. The water molecules simply gain enough energy to break away from their liquid state and become a gas, without any new substances being formed.
What light can humans not see and how does it impact our understanding of the world around us?
Ultraviolet light is a type of light that humans cannot see, but many animals can. This impacts our understanding of the world around us because there are things happening in nature that we cannot perceive without the ability to see ultraviolet light. For example, some flowers have patterns that are only visible in ultraviolet light, which helps attract pollinators. By not being able to see ultraviolet light, we may be missing out on important information about the natural world.
How does energy change from one form to another in nature?
In nature, energy can change from one form to another through processes like photosynthesis, where light energy is converted into chemical energy in plants. This energy transformation occurs in various ways, such as through heat transfer, chemical reactions, and mechanical work, following the laws of thermodynamics.
Is Sunlight an example of an electromagnetic wave in nature?
Yes, sunlight is an example of an electromagnetic wave in nature. It consists of a combination of different wavelengths of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation.
X-rays and ultraviolet light can change the chemical nature of DNA?
photosynthesis
X rays ultraviolet light and radioactive substancesthat can chage the chemical nature of DNA are classified as?
X-rays, ultraviolet light, and radioactive substances that can change the chemical nature of DNA are all classified as mutagens. These agents can induce changes in the DNA sequence, leading to mutations that can have various biological consequences.
How can you tell chemical change?
The consequence of a chemical change is the modification of the molecular nature.
In a chemical change the identity of matter does not change?
No, the chemical nature of the reactants is changed.
Why is water evaporating in the atmosphere a physical change?
Because the chemical nature of water molecules is unchanged.
Why is salt water considered a physical change?
Dissolution is a physical change because the chemical nature of salt remain unchanged..
How is chemical change different from physical change?
During a chemical change the nature of substances is changed.
Is bouncing a ball a chemical change?
yes No. Nothing changes in its chemical nature.
How do you know rusting on a nail is a chemical change?
Rusting on a nail is a chemical change because it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide. This process is irreversible and results in a change in the chemical composition of the nail.
What best exhibits a chemical change?
The chemical nature of the molecule is transformed.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
Is eggs turning into omlettes a physical or chemical change?
It is chemical because the nature of the chemical has changed.Physical changes including chopping, grinding, dissolving, melting, freezing, and boiling. An omlette cannot be turned back into an egg. The egg protein has changed its chemical nature. Physical change alters the form or appearance of a material without changing the chemical composition.
