When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
When a substance goes directly from a solid state to a gas state as dry ice does .?
It's called sublimation. Its undergoing a phase change. -APEX:)
Is melting ice cube a physical change?
Yes, melting an ice cube is a physical change because the substance is undergoing a change in state from a solid to a liquid without altering its chemical composition.
Is evaporation a chemical property or a physical property?
Evaporation is a physical property. It is the process by which a substance transitions from a liquid state to a gaseous state without undergoing a chemical change.
When a substance is undergoing change of state the temperature of the substance does not change until the is complete?
During a change of state, such as melting or boiling, the temperature of the substance remains constant because the heat energy is being used to break intermolecular forces rather than increase the kinetic energy of the particles. Once the change of state is complete, the temperature will start to rise again as thermal energy is being used to increase kinetic energy.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
What is happening to a substance undergoing heat of fusion?
During the heat of fusion, a substance is transitioning from a solid phase to a liquid phase. The heat energy is being absorbed by the substance, causing the particles to break free from their fixed positions and begin to move more freely. This results in a change in the physical state of the substance without a change in temperature.
Is vaporize a physical change?
Yes. Liquid or solid changes to a gas physically.
How does the rearrangement of water molecules change state of matter?
There are empty spaces between the particles of matter that are very large and that can be used to identify a substance because they never change.
Why does the temperature of body remain steady when the body is undergoing a change in state?
5620
When ethyl alcohol evaporates is it a chemical or physical change?
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
What is the change of a substance from one physical state to another?
change of state
