Webb28 sep. 2024 · How do you calculate heat in physics? The amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcΔT, where m is the mass of the … Webb29 sep. 2024 · What is the q of an electron? electron charge: e=-1.602 x 10-19 Coulombs. One coulomb (C) of charge represents an excess or deficit of 6.24 x 10¹8 electrons. The quantity of charge (Q) on an object is equal to the number of elementary charges on the object (N) multiplied by the elementary charge (e). postulates in geometry definition

WebbR. Electric Energy. The electric energy delivered by an electric current is the product of its power and time over which it flows — and therefore the product of…. voltage. current. … WebbQ = mcΔT m = 1, c = 4186, and ΔT = 10°. Q = 41860 J Calculate the change in entropy for the hot and cold water using the equation: ΔS = Q/Tavg The T's are in kelvin. For the cold water, Tavg= 22°C = 295 K. Q is positive for the cold water, because heat was added, and negative for the hot water. ΔScold+ ΔShot= 41860/295 - 41860/305 = +4.65 J/K.
