As for the second question, According to "Marks' Standard Handbook for Mechanical Engineers", 10th, coal gas burns at about 3,590°F (1,977°C) under 100% air conditions. More or less air will decrease the temperature. This means that the maximum temperature of a coal fire in a forge is about 3,500°F (1,927°C). Then it is funneled through and you heat a liquid like water up even more (like if you put it in a pot on the stove), then the molecules will move around so fast that they can’t even hold on to each other at all. When this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam). The process of gas molecules leaving the liquid to go into the gas is called "evaporation." Then the steam-driven piston and cylinder is delivering energy to the machine it powers only 50 percent of the time (during the power stroke, when the steam is actually pushing it); the rest of the time, it's being pushed back into the cylinder by momentum ready for the next power stroke.

Answer 2

The answer is transporting.
