How does an earthen pot keep water cool? This is how I understand it: Evaporative cooling can reduce the temperature of some object to below ambient temperature. Evaporation is an endothermic process that removes energy from the object. Molecules in a liquid are constantly colliding and transferring energy back and forth. Water molecules leaving the surface have higher energy than molecules remaining in the liquid state. These higher energy molecules have left the liquid and can no longer transfer that higher energy back to the other molecules. The remaining molecules collectively have less energy. |

How does an earthen pot keep water cool? See Matki "The cooling process works through evaporative cooling. Water seeps from mini-pores in the pot and evaporates, thus making the water inside cooler than the outside temperature" |

Capacitor Charging and Discharging when connected to the ground AFAIK charge doesn't flow (to any significant extent in this context) unless you have a circuit. Connecting one end of a charged capacitor to anything has no significant effect. The explanation about a flow of charge causing D+ to be 0V is spurious. Voltage is relative to a reference point, any point on your collection of capacitors can be considered 0V without needing charges to move. |

Carbon in the form of graphite a conductor? @Favner: Graphite is much more conductive than semiconductors such as silicon - see Resistivity of various materials and List of semiconductors |

Carbon in the form of graphite a conductor? If your multimeter reads 0.6V you are probably using the "diode test" function when you should be using the "resistance"/"ohms" function. The "continuity test" function is often at the same dial position as diode test. continuity just beeps if resistance is less than some threshold (e.g. 50 ohms). Use the "ohms" function. |

Why are electrons in one atom attracted to negative electrons in another atom? The electric force is just something that is observed in nature, given a name, studied and modelled mathematically. |

Can thought experiments qualify as actual research? "unless they're working in" ? - software? Nebraska? playdough? conjunction with cats? academia? a dumpster? |

If there's a light ray and it's turned to a new location by a certain angle @Artur: The principle is the same as if you are looking at a torch in my hand and I turn the torch off. You don't find out about it until $x/c$ seconds later (ignoring relativistic effects and assuming we're in a vacuum etc etc). Photons currently travelling in your direction are unaffected by subsequent torch waggling. You may need to edit your question and add a diagram and a more careful explanation of what is puzzling you. |
