Iron-Carbon Phase Diagram (a review) see Callister Chapter 9

The Iron–Iron Carbide (Fe–Fe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.

Flotation in boat hulls - Glen-L Boat Plans

Everyone must admit that having positive flotation value aboard a boat is a good quality, and in theory, enough flotation material or devices can conceivably make a boat that is IMPOSSIBLE to sink. Yet for every cubic foot of flotation value added, we must also give up that amount of space in our boat that could be used for something else.

Electrodes and voltage of Galvanic cell (video) | …

In the last video, we talked about how we could create a voltaic cell or galvanic cell or essentially a battery by separating the oxidation and the reduction reactions and connecting them with a wire, which forces the electrons that zinc is losing to go through the wire to go to the copper ions so that they can get them, so the copper ions can be reduced.

1.2 Phases and Classification of Matter – Chemistry

Matter is defined as anything that occupies space and has mass, and it is all around us. Solids and liquids are more obviously matter: We can see that they take up space, and their weight tells us that they have mass. Gases are also matter; if gases did not take up space, a balloon would stay collapsed rather than inflate when filled with gas.
