change is complete
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
Sensible heat involves a change in a substance's temperature without a change in its phase. It is the heat exchange that causes a change in the temperature of a substance but does not result in a change of state (solid, liquid, gas).
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
break intermolecular bonds and change the phase of the substance rather than increase the kinetic energy of the particles (temperature).
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.
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
During a phase change, the kinetic energy of particles remains constant. This energy is used to break or form intermolecular bonds, causing the substance to change from one phase to another without a change in temperature.
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
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.
