True!
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
No, the properties of a substance do not change when it is mixed with another substance. The substances retain their individual properties even when they are combined. Mixing substances simply results in a physical change, without altering their individual properties.
no
True
a physical change is a change in any physical property of a substance, not in the substance itself
It's called a physical change.
no, if it's a substance change then it's a chemical change. If it were a physical change then it would be the same substance
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
physical changes do not change the chemical properties of a substance
When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
it would be physical change because physical change is when the substance stays the same
chemical change
maybe..
