What else can I help you with?
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
What happens when a pure substance undergoes a chemical changes?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
Does the element change when the atomic mass changes?
No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.
What kind of change such as a change of state the substance of the whole changes but its underlying structure remains the same?
In changes in which the molecular structure of a substance remains constant, such as changes of state, we often refer to these changes as Physical Changes. If the molecular structure is altered it would be a Chemical Change.
What happens to a substance in physical change?
it means figure it out yourself!

Are the atoms in a substance the same if the substance changes states?
On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.
What does not change when a substance changes matter?
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.

What happens to the overall mass of a substance when it changes state?
The overall mass of a substance remains the same when it changes state. The mass is conserved during physical changes like melting, freezing, vaporization, or condensation. This is because the number of atoms or molecules in the substance does not change during a change in state.
What is called a change that does not make a substance into a new substance?
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.
