WebSep 12, 2024 · We first consider ΔS for a system undergoing a reversible process at a constant temperature. In this case, the change in entropy of the system is given by ΔS = Q T, where Q is the heat exchanged by the system kept at a temperature T (in kelvin). If the system absorbs heat—that is, with Q > 0 - the entropy of the system increases. WebSo if P P represents power in watts, \Delta E ΔE is the change in energy (number of joules) and \Delta t Δt is the time taken in seconds then: P = \frac {\Delta E} {\Delta t} P = ΔtΔE There is also another unit of power which is still widely used: the horsepower. credit card with good credit
