The transformation of a liquid to a gas.

∙ 12y agoThe change that occurs is that it will look different; although the atoms in the item did not change like a piece of ripped paper. The shape of the full paper has turned into halves, and the atoms were separated. For example, frozen water is a physical change because it looks different. But the atoms did not change, it was just the temperature.

Physical change is a change of the state of matter (melting, freezing, boiling), form (grinding, cutting, etc.), etc. A physical change does not involve the chemical nature of the molecules; the molecules remain unchanged.

What physical changes happens during evaporation?
The transformation of a liquid to a gas.
What is a characteristic that best describes what happens during a physical change?
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
What happens when you turn solid into liquid into a gass?
These are changes in physical state, which are physical changes.
Which changes occur during evaporation?
During evaporation, liquid water gains enough energy to break free from the surface of the liquid and turn into water vapor. This process involves the transfer of heat energy from the surroundings to the liquid. As a result, the liquid slowly decreases in volume and the temperature of the remaining liquid may decrease due to the loss of heat energy.
What happens to the characteristics of a substance during a physical change?
During a physical change, the characteristics of a substance such as size, shape, and phase may change, but its chemical composition remains the same. These changes are reversible and do not result in the formation of a new substance.
What happens to copper when it turns green?
Physical Changes
What happens to mass during chemical and physical changes. explain?
Law of Conservation of Mass: mass can not be created or destroyed, it can only be changed (transformed).
How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
During an energy change?
During an energy change, the energy of a system is converted from one form to another, such as from potential to kinetic energy. This transformation can occur through various processes, including work done by external forces or heat transfer between the system and its surroundings. The conservation of energy principle states that the total energy of a closed system remains constant during these changes.
Is evaporation of gasoline a example of physical change?
Yes, evaporation of gasoline is an example of a physical change because it involves the substance changing state from liquid to gas without altering its chemical composition.
What happens to the energy that is released during an earthquake?
It is dissipated in making physical changes to the rock layers, and to the ground surface, objects, and buildings. Some is released as thermal energy.
