How does heat move from one end of a solid to the other?
Heat moves through a solid by conduction, where energy is transferred through direct contact between atoms and molecules. As one end of the solid gains heat energy, the atoms vibrate more, passing energy to neighboring atoms and so on, eventually reaching the other end of the solid. The rate of heat transfer depends on the material's thermal conductivity and the temperature gradient.
Does melting lose or gain energy?
Melting gains energy because it requires heat energy to break the intermolecular forces holding together the solid molecules. This energy is needed to overcome the attraction between the molecules and allow them to move more freely as a liquid.
What happens when heat energy is taken from a liquid?
When heat energy is taken from a liquid, the temperature of the liquid decreases, causing the molecules to slow down and come closer together. If enough heat is removed, the liquid can eventually freeze and become a solid.
What are two phase changes that occur when matter loses heat energy?
Two phase changes that occur when matter loses heat energy are: Solid to liquid: When a substance loses heat energy, it can transition from a solid phase to a liquid phase. This process is called melting. Liquid to gas: Another phase change that can occur when matter loses heat energy is the transition from a liquid phase to a gas phase. This process is known as vaporization or boiling.
Why is heat energy needed to melt a solid. What is this heat energy called?
Heat energy is needed to melt a solid because it provides the molecules in the solid with enough kinetic energy to overcome the forces holding them in a rigid structure. The specific heat energy required to melt a solid at its melting point is called the latent heat of fusion.
When heat is applied to an object it can become a liquid. what is this?
This process is called melting. When heat is applied to a solid material, it gains enough energy to overcome the forces holding the molecules in a solid-state, allowing them to move freely and transform into a liquid state.
What does a liquid to a solid involve in thermal energy?
To become a solid, a liquid will absorb heat energy.
When a solid gains heat energy its molecules begin vibrating too quickly to stay together so the solid becomes an?
When a solid gains heat energy, its molecules vibrate more rapidly, eventually overcoming the forces holding them together in a fixed position. This leads to the solid melting and transforming into a liquid.
A liquid become a solid when there is more heat This causes the molecules to move rapidly?
Actually, a liquid becomes a solid when it loses heat, not when it gains heat. When heat is removed, the molecules slow down and eventually arrange themselves into a solid crystalline structure.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
Does vaporization require loss of heat energy?
No, but instead it gains heat energy
How does heat move from one end of a solid to the other?

The rate of heat transfer depends on the material's thermal conductivity and the temperature gradient.
What does a solid do when you add heat to it?
When heat is added to a solid, its particles vibrate faster and the solid gains energy. This increased energy causes the solid to expand slightly as the particles move farther apart. If enough heat is added, the solid may reach its melting point and transition into a liquid state.
When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid
Does melting lose or gain energy?
Melting gains energy because it requires heat energy to break the intermolecular forces holding together the solid molecules. This energy is needed to overcome the attraction between the molecules and allow them to move more freely as a liquid.
When a solid gains heat energy it's molecules begin vibrating too quickly to stay together so the solid becomes a?
it becomes a liquid, and then a gas after that if heated even more.
What has to be removed from milk for it to become a solid?
