The temperature of a gas at 1.00 atm and 8.00 °C is increased to 20.0 °C, resulting in a change of pressure.Which equation would you use to calculate the new pressure? A) P_iV_i = P_fV_f B) P_i/V_i = P_f/V_f C) P_iT_i = P_fT_f D) P_i/T_i = P_f/T_f E) V_i/n_i = V_f/n_f

The correct equation to use is the combined gas law, which relates pressure, volume, and temperature changes in a gas. Since the volume is not mentioned as changing, and the number of moles (n) is constant, the appropriate form simplifies to $P_1/T_1 = P_2/T_2$, which is represented by choice D. This equation allows for the calculation of the new pressure after a temperature change when the volume is constant.
