Question

Assuming all have the same initial volume, compare the following substances by the amount of volume expansion due to an increase in temperature: glass, mercury, aluminum, ethyl alcohol. (See the table below. Select all that apply.)

Ethyl alcohol would have the smallest expansion.
Ethyl alcohol would have the largest expansion.
Mercury would have the smallest expansion.
Mercury would have the largest expansion.
Glass would have the smallest expansion.
Glass would have the largest expansion.
Aluminum would have the largest expansion.
Aluminum would have the smallest expansion.

Here is the table http://www.webassign.net/sercp8/10-table-01.gif

Explanation / Answer

The solids in the table of coefficients of linear expansion while the liquids and gases have coefficients of volume expansion. For solids, cofficient of volume expansion can be approximated to be 3 times as much as the coefficient of linear expansion.

So, glass would have the smallest expansion and mercury would have the largest expansion.
