What happens to a substance in physical change?
it means figure it out yourself!
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No, that statement is incorrect. A physical change does not involve changing the composition of a substance or forming new substances. It only alters the physical state or appearance of a substance without changing its chemical composition. When a substance changes composition and forms new substances, it is considered a chemical change.
How does the motion and arrangement of particles is a substance change as the substance freezes?
As a substance freezes, the particles slow down and move closer together, forming a more ordered arrangement. This results in a decrease in the substance's volume and a transition from a liquid to a solid state.
Enthalpy changes accompanying a change of state are than those accompanying the heating of a substance at each state?
The enthalpy changes accompanying a change of state (e.g., melting, boiling) involve breaking or forming intermolecular forces, which may require more energy than simply raising the temperature of a substance at that state. This is because changes of state involve a phase transition, which requires additional energy to overcome the intermolecular forces holding the substance together.
How do energy and changes in energy change the state of matter?
Energy can change the state of matter by breaking or forming intermolecular bonds. Adding energy to a substance can overcome the forces holding the molecules together, leading to a phase change (solid to liquid, liquid to gas). Removing energy from a substance can cause the molecules to come closer together, resulting in a phase change in the opposite direction.
Is juice freezing and forming popsicles a physical or chemical change?
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
What is a change in some properties on matter without forming a diferenct kind of matter called?
A change in some properties of matter without forming a different kind of matter is called a physical change. This can involve changes in state, shape, size, or appearance of the substance, but the chemical composition remains the same.
What is the change of a substance from one physical state to another?
change of state
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
Is melting iron physical change or physical property or chemical change or chemical property?
Melting iron is a physical change because it does not alter the chemical composition of the iron. It is a change in state from solid to liquid without forming a new substance.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
Is a Chemical change of pizza Paper and An iron nail or of Physical change?
The chemical change of pizza, paper, and an iron nail would lead to a new substance(s) being formed with different properties than the original materials. A physical change, on the other hand, involves a change in the physical state or appearance of a substance without forming a new substance.
