) The (Hoplite) Phalanx, while most known as an incredible defensive unit, was an equally powerful attacker against enemy melee or inferior formations (Warriors). Clashes would result in the front lines of inferior formations being crushed, and an enemy melee would be easily routed.

) Iron is not really stronger than bronze. However, it's plentiful, cheaper, and easier to work.

) Steel Working has actually been known for millenia in certain circles. However steel was not perfected or industrially viable until the mid-late 1800s when the Bessemer Process was created and perfected.

) Guns were originally made with bronze, not wrought iron, until quality steel became available around the turn of the 20th century. This form was called 'gunmetal' and included a small amount of zinc to resist corrosion.

) Frigates use cannons.

) Ironclads were developed simultaneously with the Bessemer Steel Process. The first ironclad was a wooden steamship(frigate) that still had sails with wrought iron armor plating, then under a year later a model made with an iron hull was launched(but still with sails). Within a few years sails were abandoned and the cannons were brought to a higher deck for better traverse. Additionally, metallurgy began advancing enough to work out the problem of making steel less brittle. Within a few decades they were replaced with more standardized cruiser and battleship designs. (Destroyer?)

) Refrigeration is actually very, VERY similar to a steam engine, but in reverse. However, (phase) volatile chemicals are also needed, and electricity is required to make it commercially viable.

) Nuclear power plants don't use refrigeration, and instead control bars to keep them from overheating. Most heat is directed into the water as part of a gigantic steam engine system.
