What happens to partials of a solid as thermal energy is added and the solid undergoes a phase change?
Define the Law of Conservation of Energy.
If someone can help me with these questions, that would be great!
once is enough, thank you.
Those who can help probably only want do do it once for each question.
1. Read up on the Kinetic Molecular Theory.
2. Look on Google. Definitions galore.
My apologies! I didn't mean to post it twice. I'm not really used to jiskha on my phone, haha!
Thanks for the help though!
To understand what happens to particles of a solid as thermal energy is added and the solid undergoes a phase change, we should first discuss the concept of phase change.
When a solid is heated, its temperature increases, but when a certain threshold called the melting point is reached, the solid starts to change its phase and becomes a liquid. During this phase change, the thermal energy being added is used to break the intermolecular bonds holding the particles together in a lattice structure. Once all the bonds are broken, the particles in the solid are free to move and slide past one another, resulting in the solid becoming a liquid.
During this phase change, the temperature of the substance remains constant even though heat is still being added. This constant temperature is called the "melting point" or "boiling point" depending on whether the phase change is from solid to liquid or from liquid to gas, respectively.
In summary, as thermal energy is added to a solid undergoing a phase change, the intermolecular bonds are broken, and the solid transitions into a different phase, such as a liquid or gas.
Now, let's define the Law of Conservation of Energy.
The Law of Conservation of Energy states that energy cannot be created or destroyed but can only be transferred or transformed from one form to another. It is a fundamental principle in physics. According to this law, the total energy of an isolated or closed system remains constant over time.
In other words, the total amount of energy within a system remains unchanged, even if energy is transferred between different objects or converted from one form (such as thermal, mechanical, or chemical) to another.
This law is based on the principle that energy is a fundamental property of the universe and is always conserved in any physical process.
I hope this explanation helps you understand the concepts better! Let me know if you have any further questions.
