Question

In which condition does moisture trapped in concrete become heated, turn into steam, and expand, causing parts of the concrete to break away?

Answer 1

Thermal stress caused by the heating and expansion of moisture trapped in concrete can lead to breakage and cracking.

Step-by-step explanation:

The condition in which moisture trapped in concrete becomes heated, turns into steam, and expands, causing parts of the concrete to break away is known as thermal stress. Thermal stress is created by the thermal expansion or contraction of a material. When concrete is exposed to high temperatures, the moisture inside it can heat up, causing it to turn into steam and expand. This expansion puts stress on the concrete, leading to cracking and breakage.
