When is expansion useful?

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 >>>>>>


How can expansion not be useful?

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.


How does amalgam have the same coefficient of expansion as a tooth and why is this useful in dentistry?

because then you know if it's on fire like jelly beans. :)


Why are bimetallic strips useful in thermostas?

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.


How the anomalous expansion of water will help in the conservation of Bio diversity?

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


How bimetallic strips are useful?

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.


Why do you use a construction joint?

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


What are substances that expand and contract called?

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.
