A19.0-l volume of an ideal gas in a cylinder with a piston is at a pressure of 2.8 atm. enough weight is suddenly removed from the piston to lower the external pressure to 1.4 atm. the gas then expands at constant temperature until its pressure is 1.4 atm. the change in the internal energy of a system, δe, for an isothermal expansion of an ideal gas is 0. use this information in your calculations for this problem.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
