Catholic church. The Dark Ages is a historical period in the first part of the Middle Ages. The term Dark Ages emphasizes the cultural and economical deterioration that occurred in Europe following the decline of the Roman Empire. In document 1 it states that many invasions broke out. The conditions in Europe were terrifying. No trading occurred‚ ceasing terror‚ and peasants abandoned fields to avoid violence. European society has no longer any government. In document 3 it describes the invasion

Diesel engines and unleaded fuel engines better known as gasoline engines are actually very similar. They are both internal combustion engines which is to convert the chemical energy in fuel into mechanical energy. This mechanical energy moves pistons up and down inside cylinders. The pistons are connected to a crankshaft‚ and the up-and-down motion of the pistons‚ known as linear motion‚ creates a force to the flywheel the from the flywheel to the transmission. The working principle of diesel engines

In the Victorian Era‚ there were many advancements in steam power. Before this era‚ “man relied on his own muscles and those of domesticated animals‚ wind‚ and water as sources of power” (Kras 6). Steam power was used for industry‚ transport‚ agriculture and generate electricity (Burton 3). Advancements in steam power enabled men to work more efficiently‚ trade goods overseas and across land faster‚ and provided transport for people. Steam power caused drastic changes such as people no longer worked

Cheryl Baclit Chem 234 Experiment 4: Steam Distillation Introduction The purpose of this experiment is to extract Eugenol from Cloves using steam distillation as a purification technique and to transfer Eugenol from the aqueous phase to the MeCl2 phase. With steam distillation‚ the boiling point of a mixture of immiscible liquids is lower than the boiling points of the individual components. Water from the steam is one of the components of an immiscible liquid mixture. The vapor pressures of
