Question

Thermal expansion occurs at __________ temperature.
1) High temperature
2) Low temperature
3) All temperature
4) none of these​

Answer 1

Explanation:

Thermal Expansion in Three Dimensions

In general, objects will expand with increasing temperature. Water is the most important exception to this rule. Water expands with increasing temperature (its density decreases) when it is at temperatures greater than 4ºC (40ºF).

Thermal expansion occurs when an object expands or gets larger due to an increase in its temperature. Thermal expansion occurs because heated molecules move faster and take up more space.

1) High temperature ✅
