What are three change of state in which energy is absorbed?
Melting: Solid to liquid transition where energy is absorbed to break intermolecular forces. Sublimation: Solid to gas transition where energy is absorbed to overcome intermolecular forces without passing through the liquid state. Dissolution: Solid dissolving in a solvent where energy is absorbed to break intermolecular forces within the solid and between the solid and solvent molecules.
What does energy do during phase change?
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, resulting in a change in the physical state of the substance (such as from solid to liquid or liquid to gas).
What happens to the energy when there is vaporization?
During vaporization, energy is used to break the intermolecular forces holding the liquid together, resulting in the phase change from liquid to gas. This energy is absorbed as heat by the substance, causing it to evaporate.
Is energy absorbed during evaporation?
Yes, energy is absorbed during evaporation. This energy is required to break the bonds between liquid molecules and change them into vapor molecules. This process is endothermic because it absorbs heat from the surroundings.
What is it called when energy is gained by something during a change of state?
The process of gaining energy during a change of state is known as endothermic phase transition. This occurs when energy is absorbed by a substance, causing it to transition from one state to another, such as from solid to liquid or liquid to gas.
During which three changes of state is energy absorbed?
cchemical change and energy change also the change of a gas to a liquid
What change phase is heat energy absorbed by a substance?
liquid to gas

What phase change will the greatest amount of energy be absorbed by 1 gram of water?
The phase change where the greatest amount of energy is absorbed by 1 gram of water is during the transition from liquid to gas, known as vaporization or boiling. This process requires a significant amount of heat energy to break the intermolecular bonds and change the water molecules from a liquid state to a gaseous state.
How can gas change back to liquid by condensation?
the vibrational energy of the molecules is absorbed in the form of heat by cooling. this brings the particles closer making them liquid.
What might happen if enough energy is absorbed by liquid water?
If enough energy is absorbed by liquid water, it will eventually reach its boiling point and start evaporating into steam. This process is known as boiling and the water will undergo a phase change from liquid to gas.

What do you call the change in state of matter from a liquid to a gas?
Condensation

Is there a release or absorption at heat in phase change?
It depends on the phase change. When going from solid to liquid (melting), liquid to gas (boiling), or solid to gas (sublimation) heat is absorbed. When going from gas to liquid (condensation), liquid to solid (freezing), and gas to solid (deposition) heat is released.
