An airplane has a half-wingspan of 40 m. Determine the change in length of the aluminum alloy [a = 22.0 × 10-6/°C] wing spar if the plane leaves the ground at a temperature of 20°C and climbs to an altitude where the temperature is -47°C. Answer: 5 - i mm

A thermometer is being designed for a process in which the temperature varies from 0 to 180 °C; from experience it is known that the process temperature, when it gets out of control, reaches up to 240 ° C. Considering that only the bulb is in contact with the part inside the equipment, what should be the volume of the safety vial? It is known that the bulb has a length of 1.2 cm and a diameter of 0.5 cm; the capillary has a length of 20 cm and the scale of the thermometer is -10 to 190 ° C. Consider that the coefficient of volumetric expansion for mercury is 1.82×10−4 ° C− 1

The digital thermometers that we use in the lab today are similar to the ones that we use in our homes, but several years ago scientists used to use glass thermometers that contained a thin column of mercury to measure temperature. Why do you think we no longer use the mercury thermometers in the lab?
