What happens to matter and the particles of an object during physical change?
The particles are affecting the form of a chemical substance and not turning into a new substance.
What is changed when matter undergoes a phisical change?
When matter undergoes a physical change (like changes in the state of matter), the space between the particles in the matter and how the particles move change.
Can matter be created or destroyed?
Matter can not be created or destroyed in a chemical or physical change. Which is known as the Law of Conservation of Mass. Matter can only be converted, this conversion happens during a chemical change.
What happens to the particles of matter when thermal energy is added to it?
When thermal energy is added to particles of matter, it causes the particles to move faster and emit more energy.
What happens to particles in matter when you remove thermal energy from them?
They stop moving and stop producing energy.
What happens to the particles of matter during a chemical change?
it will change to liquid
What happens to matter and the particles of an object during physical change?
The particles are affecting the form of a chemical substance and not turning into a new substance.
When the potential energy of a material changes what happens to the materials what of matter changes?
In a solid the particles are close together and in fixed positions In a liquid the particles are still really close together but can move around past each other In a gas the particles are free to move and far apart During a state change the particles in the substance will change from being in one of the above to another
What happens to heat during a change of state?
Heat increases the energy of in matter. This causes the movement of the particles making up the matter to speed up. The changes of state occur depending on the speed of the particles.
What is changed when matter undergoes a phisical change?
When matter undergoes a physical change (like changes in the state of matter), the space between the particles in the matter and how the particles move change.
What happens to the composition of matter during a physical change?
It can change from a gas to a solid to a liquid, or from a liquid to a solid to a gas. This change does not affect the composition of the matter.
What happens when adding heat to matter?
particles
What happens to energy when matter undergoes chemical or physical change?
Energy can either be soaked up by the matter in the process of making the change (melting), or be released from the matter during the change (fire).
If enough energy is added to matter in the liquid state it will change into different state. During this change of state the particles would?
move faster and break free from other particles, entering the gas state.
If enough energy is added to matter in the liquid state it will change into a different state during this change of state the particles would?
move faster and break free from other particles, entering the gas state.
What happens to matter during chemical change?
The chemical nature of the matter is changed; new compounds with new chemical formulas are formed.
Can matter be created or destroyed?
Matter can not be created or destroyed in a chemical or physical change. Which is known as the Law of Conservation of Mass. Matter can only be converted, this conversion happens during a chemical change.
