Discuss some of the early developments in the field of thermometry that have led to the Fahrenheit and Celsius temperature scales currently in use today.
Calculate the length of a 1-meter rod of a material with thermal expansion coefficient a when the temperature is raised from 300 K to 600 K. Taking your answer as the new initial length, find the length after the rod is cooled back down to 300 K. Is your answer 1 meter? Should it be? How can you account for the result you got?
Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.

Solve the common pressure and temperature assuming no heat loss in the containers and the surrounding of the two containers A and B that hold an ideal gas at pressure PA and PB, and absolute temperature TA and TB respectively. The containers are connected by a thin tube (and a close valve). The valve is opened to allow the pressures and temperatures to equalize.
