Question
As a result of thermal expansion, solids experience a change in _____.
- Length
- Area
- Volume
- All of the above
Hint:
At higher energy levels, the average atom separation is also larger. When you increase the temperature for most objects, they expand.
The correct answer is: All of the above
- Thermal expansion can be defined as the change in the length, width, height, or volume of any material on changing the temperature.
- Higher temperatures mean higher energy levels. At higher energy levels, the average atom separation is also larger. When you increase the temperature for most objects, they expand.
