Answer: The gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases. Gases behave in a similar way over a wide variety of conditions because they all have molecules which are widely spaced, and the equation of state for an ideal gas is derived from kinetic theory. The earlier gas laws are now considered as special cases of the ideal gas equation, with one or more variables held constant.

The conquistadors built homes, farms, chapels and other buildings using building patterns and designs similar to those in Europe. The soldiers also brought new weapons that helped the indigenous people to fish and hunt with greater ease.
The Qin dynasty was the first dynasty to start connecting the various walls into a greater whole. That happened around 221 to 206 BC and was done under the reign of Qin Shi Huang. Though the wall was later improved still by other dynasties, it was during the Qin dynasty that the Great Wall of China was first formed into a cohesive structure.
