As you are heating a piece of metal, you notice that its size increases as its temperature increases. Which statement best explains the rationale for this observation?QUESTION 4ANSWERa.Heating increases the mass of the metal, leading to larger size.b.Heating causes the metal to become denser, leading to an increase in size.c.Heating causes the metal atoms to vibrate with reduced amplitude, resulting in expansion of the metal.d.Heating causes the metal's particles to move faster and further apart, resulting in expansion.
Question
As you are heating a piece of metal, you notice that its size increases as its temperature increases. Which statement best explains the rationale for this observation?QUESTION 4ANSWERa.Heating increases the mass of the metal, leading to larger size.b.Heating causes the metal to become denser, leading to an increase in size.c.Heating causes the metal atoms to vibrate with reduced amplitude, resulting in expansion of the metal.d.Heating causes the metal's particles to move faster and further apart, resulting in expansion.
Solution
The best explanation for the observation that a piece of metal increases in size as its temperature increases is: "Heating causes the metal's particles to move faster and further apart, resulting in expansion."
Here's why:
-
When you heat a piece of metal, you're adding energy to it. This energy is transferred to the metal's atoms, causing them to move more rapidly.
-
As the atoms move faster, they also move further apart from each other. This is because the increased energy allows them to overcome the forces that normally keep them close together.
-
As the atoms move further apart, the metal as a whole expands. This is why the size of the metal increases as its temperature increases.
So, the statement "Heating causes the metal's particles to move faster and further apart, resulting in expansion" best explains the observation.
