Solution: Click For PDF Version
Let A
be the cross-sectional area of the tube. The volume of the liquid,
The change in
the volume of the liquid when it is heated to
Therefore,
the volume of the liquid at
The
cross-sectional area of the glass tube would also increase due to
thermal expansion when the tube is heated to
And
Let the
height of the liquid column in the glass tube at
Then
Therefore, the change in height of the liquid in the glass tube will be
|
.
We have to find the change in height of the liquid column when the
tube is heated to
.
We may assume that
and
