heat is produced
When energy is added during a phase change the energy is used to break molecular bonds.
When energy is added during a phase change the energy is used to break molecular bonds.
The potential energy of the molecules change during a reaction.
The energy change that occurs during condensation is: temperature.
when a chemical change occurs, chemical bonds are broken up
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
During a phase change, energy is either absorbed or released as heat without causing a change in temperature. This energy is used to break or form intermolecular bonds between molecules, rather than increasing the average kinetic energy of the molecules.
The temperature* remains unchanged. * The heat (energy) content changes.
Kinetic Energy is gained in the foward changes and lost in the reverse changes of state
During a phase change, the temperature remains constant as the substance absorbs or releases heat energy to change from one phase to another. This is because the energy is used to break or form intermolecular bonds rather than raise or lower the temperature.
During the state change, it's kinetic energy stays constant as well as it's heat. But potential energy is the one to rise.
