Expansion may not be useful if it leads to unsustainable growth, stretching resources thin, causing quality to decline, or losing focus on core objectives. It can also be detrimental if not carefully planned and executed, resulting in increased costs without corresponding benefits. Additionally, expansion can create added complexities and challenges that may outweigh the potential advantages.
Bimetallic strips are useful in thermostats because they bend when heated, allowing them to trigger switches or valves to control temperature. The differential thermal expansion of the two metals in the strip enables precise temperature sensing and regulation within a thermostat.
Bimetallic strips are useful because they are designed to bend or curl when exposed to temperature changes, due to the different thermal expansion coefficients of the two metals they are composed of. This bending action can be used in devices such as thermostats to control temperature, switches to break or complete an electrical circuit, or in mechanical gauges to indicate temperature changes.
The work of gas expansion can increase the overall efficiency of a thermodynamic system by converting the energy of expanding gas into useful work. This work can be harnessed to perform tasks such as generating electricity or powering machinery, leading to improved efficiency in the system.
All solids expand as they are heated but I guess you want some examples where this is either useful or a problem: Useful * Bimetalic strips used in thermostats. They are made by joining 2 metals with different rates of expansion together, as they get warm they bend one way, as they get cold they bend the other. Problem * Long pipes have to have S bends in them to allow for the expansion/contraction otherwise they buckle or snap. * Railway lines are laid with gaps in them so that there is room for them to expand. (This is where the ta ta ta tap sound comes from as the wheels go over the gaps.) * Bridges have to have be suspended to allow for expansion.
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
Expansion is useful because it is used for lots of thing such as blowing up tires, balloon's, and much more.TYLERNBIS
Boiling of materials like egg.
like peanut better
When things expand, it can block certain things out like a machine
Tis useful very much indeed, specially in the times blacksmiths rather have to create certain objects and use expansion. Tis great because they can mould things once they've expanded. So YAH >>>>>>
because then you know if it's on fire like jelly beans. :)

the anomalous expansion of water is where water contracts from 0to 4 degrees and then expands.In winters when the large water bodies turn deadly cold,the anomalous expansion of water helps in freezing only the top layer of the water bodies so that the marine life can survive underneath.This is how the anomalous expansion of water is useful in conservation of bio diversity

Construction joints are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL
Materials that expand and contract in response to changes in temperature are typically referred to as thermal expansion materials. These materials expand when heated and contract when cooled, which can be useful in various applications such as in thermostats, bimetallic strips, and expansion joints.
Printing presses is correct in this case.... (Found in another website. people found it useful.)
