Water is interesting in that it expands when it freezes, while most material contract, due to its dipole. In liquid state, the molecules are actually more closely packed than in an ice crystal. In liquid water, there is still a lot of space between the molecules. For example, 1L of alcohol poured into 1 liter … Read more

Technically a cell does reduce entropy in some cases (many subsystems do this), whereas the life form typically on the hole increases entropy in the environment, by creating heat. In building itself, a lifeforms stores energy in the chemical bonds making up fats and proteins etc, seemingly violating thermodynamics. In fact, as an animal cell … Read more

Quick Answer:To obtain actual numbers for voltage with a wire moving through a magnetic field it is a cross product of velocity, field strength, resistance etc. For a simpler calculation use Voltage = vBL, velocity of wire (m/s), magnetic field strength (Tesla) and length(meters). This assumes a wire moving perpendicular to a uniform field. For engineering design, … Read more
