What happens to a substance in physical change?
it means figure it out yourself!
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
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.
When using the particle model of matter to describe what happens to the density of a substance when it cools?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
What happens when a physicial change occurs?
During a physical change, the substance undergoes a change in its physical properties such as shape, size, or state of matter without altering its chemical composition. No new substances are formed during a physical change. Examples include melting ice, boiling water, or tearing a piece of paper.
Change 3 explain what happens to the identity of a substance in a physical change 4- explain what causes a substance to change from one state to another 5- explan what happens to particle size?

What happens when to particles of a substance when it condenses?
Particle Movement decreases.

What happens when a substance undergoes a physical change?
During a physical change, the substance's chemical composition remains the same. It undergoes a change in physical properties such as shape, size, or state (solid, liquid, gas) without forming a new substance. Examples include melting, freezing, boiling, and dissolving.
What happens to a particle of a substance when it expands?
individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with). If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)
What happens when a substance undergoes thermal expansion?
When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
What happens when carbon 14 undergoes radioactive decay?
6C14 ---------> 7N14 + -1 e0 Beta particle is emitted and carbon changes into nitrogen
What happens when a pure substance undergoes a chemical change?
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
