Question

Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids.Type 1 for true and 0 for false

Answer 1

Thermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids.

One disadvantage of expansion is that roads crack during the cold season because they contract and expand during the hot summer. This expansion can make the road surfaces rough. Metal and steel structures used in bridges also expand when they heat up, causing fractures in the bridge.

Another disadvantage is of cracking of thick walled glass tumbler. A thick walled glass tumbler often cracks. When very hot liquid (tea or water) is poured into it, this can be explained as follows:

When a hot liquid is poured into a thick walled glass tumbler, its inner wall gets heated, while the outer walls remains at room temperature this causes a sudden expansion of the inner side, the outer side remaining unaffected. This unequal expansion of two sides produces stain in the glass and thus it cracks.
