Quiz #2
A glass flask whose volume is 1000.00 cm at 0.0°C is completely filled with mercury at this
temperature. When flask and mercury are warmed to 55.0°C, 8.95 cm3 of mercury overflow.
Compute the coefficient of volume expansion of the glass. (B-s= 18 x 10-6K-1)

Thermal Expansion of Water, Thermal Stress Young and Freedman, University Physics 13th
ed Section 17.4 Work out Example 17.4
Thermal stress
o If we hinder an object from expanding or
contracting, tensile or compressive stresses develop
These stresses are called thermal stresses Note that stress is a form of pressure, not force!
Thermal stress
u Thermal stress is given by
T.S.= = = -Ya dT
O Y = Young's Modulus (recall Physics 71).
A = cross-sectional area
