The answer is glyceride, hope I helped
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral
Introduction of essay: talk about the three models used in science (mathematical, conceptual and physical), how do they help scientists understand complex ideas?, introduce the formula for density (as a mathematical model) and the particle model (as a conceptual model ... i think it is...) in science.
Body paragraph of essay: further discuss the properties of the models, link them to the examples (formula of density and the particle model) and compare and contrast (the strengths and weaknesses of each model) e.g. “Mathematical models help scientists to understand the underlying relationship between two concepts. Although a mathematical model is short and concise it is often hard to describe the model conceptually or physically and its therefore harder to get the full picture of how a scientific process works physically. A conceptual model is helpful for intuitive ideas in science like the particle model that would be harder to describe mathematically, due to how broad it is.” Etc etc.
Conclusion paragraph of the essay: “to conclude, models in science are important because they help us to understand difficult and intuitive ideas in a more clear and concise manner.” Etc etc.
Hope this helped - keep in mind that i don’t know the actual difference between conceptual and physical models so look through your books notes for more info for your essay.
Energy transferred into the system is wonderful due to the fact the system ends up with greater strength while energy transferred out from the machine is negative, because the device finally ends up with much less energy.
In defining work, we awareness at the outcomes that the system (e.g. an engine) has on its surroundings. for this reason we outline work as being fine when the gadget does work at the environment (strength leaves the machine). If work is completed at the gadget (energy added to the machine), the work is bad.
The classical sign convention states that warmth switch into a device and work produced with the aid of it are tremendous, while heat transfer faraway from a device and work produced on it is negative.
Q is wonderful if warmness is added into the device from the surroundings. The take a look at tube would feel cooler if the response had been being finished in one. If the surroundings is tormented by the machine, work is poor. This indicates that energy is escaping the system.
