Its released or adsorbed. Its "physical" because no new substance(s) is produced.
What changes and what remains the same during a physical change
The potential energy of the molecules change during a reaction.
Energy either transfers to the object or leaves the object.
The energy change that occurs during condensation is: temperature.
Physical Change
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
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).
What changes and what remains the same during a physical change
The conductor of energy is not a physical change. The conduction of energy happens due to a chemical bonding of specific metals. A conductor of energy produces a flow of electrical charges.
During any chemical or physical process, the energy of the universe remains unchanged.
When energy is added during a phase change the energy is used to break molecular bonds.
no
