Calculate the change of internal energy of 10 kg of air modeled as the ideal gas in a closed system when the air temperature decreases from 800 K to 500 K and the specific heat ratio is 1.37.
WebIn this equation, U = internal energy c = heat capacity at constant volume n = number of moles T = temperature Internal Energy Change Every substance has a definite amount … WebJan 30, 2024 · According to the first equation given, if the internal energy ( U) increases then the ΔH increases as temperature rises. We can use the equation for heat capacity and Equation 2 to derive this relationship. C = q ΔT Under constant pressure, substitute Equation 6 into Equation 7: Cp = (ΔH ΔT)P
Webnow, since there is no change in volume so workdone will be zero. now whats left is, U = Q and thermos flask is nearer to an adiabatic (isolated) system so Q will also be zero because no heat can flow in or out.therefore, Del U= 0 which means there is no change in internal energy that is remains constant.
