What is the changes in kinetic energy as a substance is heated to its melting point?
The kinetic energy increase.

What is melting or boiling point?
The melting point is the temperature at which a solid changes phases into a liquid. This is a result of the highly structured atoms of the solid, which have very little kinetic energy beginning to gain energy and dissociate. The boiling point is the temperature at which a liquid changes into a gas. This happens when the atoms/molecules of a liquid gain enough kinetic energy to escape the liquid and move into the gaseous state.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
What happen in terms of kinetic theory when you heat a substance?
When you heat a substance, its kinetic energy increases, causing the particles to move faster and further apart. This leads to an increase in the substance's temperature and potentially a change in state, such as melting or boiling.
Does melting occur when a substance changes from a liquid to a solid?
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.
What is the measurement of the average kinetic energy of the molecules of a substance?
temperature is the average kinetic energy of a particle
What are the changes in the kinetic energy as a substance is heated to its melting point?
As a substance is heated to its melting point, the kinetic energy of its particles increases, causing them to move more rapidly. This increase in kinetic energy leads to a rise in temperature until the substance reaches its melting point. At the melting point, the kinetic energy is used to overcome the forces holding the particles together, leading to the substance changing from a solid to a liquid state.
When a substance is what it gains thermal energy?
When a substance gains thermal energy, its temperature increases as the particles within the substance move faster and have greater kinetic energy. This increased thermal energy can lead to changes in the physical state of the substance, such as melting or boiling if enough energy is absorbed.
What changes when the average kinetic energy of atoms of an object changes?
When the average kinetic energy of atoms of an object changes, its temperature also changes. This is because temperature is a measure of the average kinetic energy of the particles in a substance. As the kinetic energy increases, the temperature rises, and as the kinetic energy decreases, the temperature drops.
The kinetic energy of a substance is the what kinetic energy of its particles?
The kinetic energy of a substance is the average kinetic energy of its particles.
The temperature at which the particles of a substance have more kinetic energy to transform is?
The temperature at which the particles of a substance have enough kinetic energy to transform from one phase to another is called the phase transition temperature. This temperature varies depending on the substance and the phase transition, such as melting, boiling, or freezing.
What is the kinetic energy of a substance and the kinetic energy of its particles?
The kinetic energy of a substance is the total energy associated with the movement of all its particles. The kinetic energy of individual particles is the energy due to their motion. The two are related, as the total kinetic energy of a substance is the sum of the kinetic energies of all its particles.
Water changes phases when heat is added or subtracted?
Boiling and melting are endothermic. Freezing is exothermic.
How can you add thermal energy to a substance without increasing is temperature?
You can add thermal energy to a substance without increasing its temperature by changing its phase, such as melting a solid or vaporizing a liquid. During these phase changes, energy is absorbed to break intermolecular bonds rather than increasing the substance's kinetic energy, resulting in no temperature change.
How is the kinetic energy of the particles that make up a substance different after it changes?
If you mean by heating it... When you heat a substance, the thermal energy of its particles increases. This means that the particles will move around faster as they have a higher kinetic energy.
How is melting similar to evaporation?
Melting and evaporation are both phase changes that involve a substance transitioning from a solid to a liquid state. In both processes, energy is absorbed to break intermolecular bonds and increase the kinetic energy of the molecules. The main difference is that melting occurs at a specific temperature for a given substance, while evaporation can occur at any temperature as long as enough heat energy is applied.
What is melting or boiling point?
