... Problem 20.20 Expand 1.00 mol of an monatomic gas initially at 5.00 kPa and 600 K from initial volume Vi = 1.00 m3 to final volume Vf = 2.00 m3. At any instant during the expansion, the pressure p and volume V of the gas are related by p = 5.00 exp[(Vi − V)/a], with p in kilopascals, Vi and V in cub ...

Newcomen atmospheric engine
The atmospheric engine invented by Thomas Newcomen in 1712, often referred to simply as a Newcomen engine, was the first practical device to harness the power of steam to produce mechanical work. Newcomen engines were used throughout Britain and Europe, principally to pump water out of mines. Hundreds were constructed through the 18th century.James Watt's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency. Many atmospheric engines were converted to the Watt design, for a price based on a fraction of the savings in fuel. As a result, Watt is today better known than Newcomen in relation to the origin of the steam engine.
