Yes, the temperature of a substance can change when it undergoes a state change, such as melting or boiling. During these phase transitions, the temperature remains relatively constant as the energy added or removed is used to break or form intermolecular bonds rather than increase the temperature. For example, during the melting of ice to water, the temperature remains at 0°C until all the ice has melted.
What else can I help you with?
Is condesing a chemical change?
No, it is a physical change because there is no change in chemical composition of the substance that is condensing.
Why is cutting a tree with a chain saw a physical change?
You're not changing the substance when you chop wood. Therefore, it is a physical change.
Is heat changing water to steam a chemical or physical change?
The process of heat changing water to steam is a physical change. During this transformation, water molecules gain energy and move from a liquid state to a gaseous state, but their chemical composition remains the same (H₂O). In a physical change, the substance alters its form or state without changing its chemical identity.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
When a pure substance is heated or cooled but does not change state the energy as heat is the what?
The energy as heat is being used to increase or decrease the temperature of the pure substance. This process involves changing the internal energy of the substance without causing a phase transition.
Why is a state change not a chemical change?
You're only changing the form of the substance, not the chemical compounds in it.
Is condesing a chemical change?
No, it is a physical change because there is no change in chemical composition of the substance that is condensing.
Is the change of state a physical?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
Is a physical change a change of state?
Yes, it is a physical change. For if it was a chemical change, it would not be able to change back; but when you are just changing the state of the item/substance it can be changed back.
Is a change that alters the form of a substance without changing it into another substance is called what?
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
Is State chemical or physical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
When a substance from one state of matter to another it is called?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
A change that alters the substance but does not change the substance is?
A physical change.Changes between Solid, Liquid, and Gas.
Is changing a state a physical or chemical change?
Changing state is a physical change. The chemical composition of the substance doesn't change, only the form the substance takes. Liquid water changing to ice is still water-- the chemical composition hasn't changed. An example of chemical change would be methane (CH3) burning in oxygen (O2) to form carbon dioxide (CO2) and water vapor (H2O). The methane and oxygen no longer exist as themselves but have become carbon dioxide and water vapor-- their chemical compositions have changed.
Is reactivity a physical change?
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
When a substance changes from one state of matter to another it is call?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
