Web1) This is useful if the equation of state is known. In case of an ideal gas, we can derive that d U = C V d T {\displaystyle dU=C_{V}\,dT} , i.e. the internal energy of an ideal gas can be written as a function that depends only on the temperature. Proof of pressure independence for an ideal gas The expression relating changes in internal energy to changes in … WebThe first law of thermodynamics states that: δQ=ΔU+w=ΔU+∫PdV. The box is well insulated; hence the heat supplied to the gas is zero. The work done is against the pressure of a vacuum. i.e. P = 0 Pa. δQ=ΔU+∫PdV. δQ=0=ΔU+0. Change in internal energy is zero, hence the temperature of the body doesn't change. The solution is independent ...
