The gas in a cylinder has a volume of 4 liters at a pressure of 123 kpa. the pressure of the gas is increased to 204 kpa. assuming the temperature remains constant, what would the new volume be?

According to boyle's law, pressure is inversely proportional to volume. Therefore (PV) initial = (PV) final. 123x4 = 204xV. V=123x4/204 = 2.41L.

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.
