Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).

What happens with the sulfuric acid and is it a chemical change or physical change?
The chemical reactions of sulfuric acid are chemical changes.
What happens after physical and chemical changes have occurred?
The substance will remain in its current state unless acted upon in such a way as to cause a physical or chemical change.
Is frying chicken phyical or chemical?
Frying chicken involves both physical and chemical changes. The physical change occurs as the chicken cooks and changes color and texture due to the application of heat. The chemical change happens as the proteins and sugars in the chicken undergo reactions that result in browning and flavor development.
Explain the difference between chemical properties and physical properties?
Chemical properties describe how a substance can form new substances by undergoing chemical reactions, like flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, like color, density, or melting point.
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Describe the difference between chemical and physical changes in terms of what happens to the molecule?
During a physical the molecules act or behave differently by speeding up and sowing down. A chemical change makes the molecule into a different molecule.
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
What is a characteristic that best describes what happens during a physical change?
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
Why is UV radiation penetrating though the skin a physical change?
Penetration of uv radiation is physical change as it happens physically but after penetration it also causes some chemical changes along with physical effects .
What kind of chemical change happens when something changes color?
Chemical
Cooking a chemical or physical change?
Both of those processes are parts of cooking. It depends on what you're doing. If you're melting or freezing its a physical change. If you're changing it into another substance then its chemical. A chemical change is when a substance is changed into another entirely different substance. This happens when an event occurs that changes the composition of the substance. Examples of chemical changes are color changes, absorbing energy, releasing energy, odor changes, producing gases, producing solids, and can't be easily reversed. A physical change is when there is a change is physical properties. This happens when an event occurs that doesn't change their chemical. Examples of physical changes are changes in the texture, shape, size, color, odor, volume, mass, weight, and density.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
