A o OT of 13 Which one of the following changes would cause the pressure of a gas to double assuming temperature was held constant? The volume will probably increase. Doubling the temperature would double the volume while halving the number of moles would decrease the volume by half, so the changes produced by these two variables cancel each other out. So let's let the number of moles equals n. The initial pressure equals P. The initial temperature equals t. The volume, which will remain constant, is V and the final pressure told that the final pressure is going to double, so this would be . If the temperature of a gas increases from $25^{\circ} \mathrm{C}$ to $50^{\circ} \mathrm{C},$ the volume of the gas would double, assuming that the pressure and the number of moles of gas remain constant. A. So let's let the number of moles equals n. The initial pressure equals P. The initial temperature equals t. The volume, which will remain constant, is V and the final pressure told that the final pressure is going to double, so this would be . 1.0 * 2.0 / 2.0 = 2.0 *1.0 / n2. As moles increase so does the pressure. This statement is false.
