Calculate the coefficient of linear expansion a for a 11.0 m metal bar that shortens by 0.500 cm when the temperature drops from 25.0 ∘C to 11.0 ∘C.
A length of thin wire is placed over a block of ice (or an icecube) at 0°C. The wire hangs down both sides of the ice,and weights are hung from the ends of the wire. It is foundthat the wire cuts its way through the ice cube, but leaves asolid block of ice behind it. This process is called regelation.Explain how this happens by inferring how the freezingpoint of water depends on pressure.
96 Figure 18-59 shows a composite bar of length L = L1 + L2 and con- sisting of two materials. One mate- rial has length L, and coeffi- cient of linear expansion a;; the other has length L2 and coefficient of linear expan- sion ar. (a) What is the coeffi- cient of linear expansion a for the composite bar? For a particular composite bar, L is 52.4 cm, material 1 is steel, and material 2 is brass.

The principal virtue of Pyrex glass is that its coefficient oflinear expansion is much smaller than that for ordinaryglass (Table 13–1). Explain why this gives rise to the higherheat resistance of Pyrex
One assistant poured 998.00 cm3 of liquid mercury into a 1000.00-cm3 -flask, when both the mercury and the glass were at 4.0 ◦C. The teacher, has asked you to determine the maximum temperature he can heat the system to (to the thousandth of a degree Celsius) before the mercury overflows if mercury has a coefficient of volume expansion of 18.0 * 10-5 ◦C-1 and the glass of the flask has a coefficient of volume expansion of 1.8 * 10-5 ◦C−1.
