AT the British Association which met last year in Edinburgh I suggested a thermometer of translation which should record the amount of the successive rises of temperature during the year. For this ...

The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been ...

The following thermal expansion chart compares the "Coefficient of linear thermal expansion" shown as a factor m/m.k in the table. All materials expand with changes in Temperature. Thermoplastics ...

IT is well known that invar possesses a coefficient of linear expansion which is much smaller than those of other metals, and that measurement of its expansion over a restricted range in the region of ...
