A steel rule is calibrated for measuring lengths at 20.00'C. The rule is used to measure the length of a Vycor glass brick, when both are at 20.00°C, the brick is found to be 42.70 cm long. If the rule and the brick are both at 79.00°C, what would be the length of the brick as measured by the rule? Coefficient of linear expansion a for steel is 12.0 1076 K-1 and for glass (Vycor) is 0.750 x 10-6K-1 x cm
At 19.0°C an aluminum ring has an inner diameter of 6 cm, and a brass rod has a diameter of 6.090cm. Keeping the brass rod at 19.0°C,to what temperature must the aluminum ring be heated toallow the ring tojust slip over the brass rod? Final answer should be in F.
5E. When a mercury-in-glass thermometer is overheated, the top will break off due to the pressure increase from the expansion of mercury which has completed filled the volume of the capillary. A thick, well-tempered glass tube may withstand a maximum pressure of 50 atm without breaking. How far can a thermometer be heated past the temperature at which a capillary is filled before the pressure becomes this large? For mercury, a=1.8x10ª K' and K=3.9x106 atm"'
