Initially at constant temperature ,
By Boyle's law we have
P1V1 = P2V2
and final pressure is doubled in this case
so , P1V1 = 2P1V2
V1 = 2V2
when at this volume of gas , temperature is getting half at constant pressure it means ,
by Charles law ,
T V
so, T3/V3= T4/V4
so , 2T3 / V1 = T3/2V4
wherr V4 is the final volume of gas
so, V4 = V1 / 4
i e volume is getting 1/4 of initial
so Correct option is
The final volume of the gas is one - fourth the initial volume

For a fixed amount of gas, if the absolute temperature of the gas is doubled, what happens to the pressure of the gas? A) The pressure of the gas becomes four times the original pressure. B) The pressure of the gas becomes double the original pressure. C) The pressure of the gas becomes triple the original pressure. D) The pressure of the gas becomes one half the original pressure. E) The answer cannot be determined without volume information.
For a fixed amount of gas at a fixed temperature, what will happen if the volume is doubled? The pressure exerted by the gas will remain unchanged. The pressure exerted by the gas will halve. The pressure exerted by the gas will double. The pressure exerted by the gas will quadruple. Which of the gases would have the fastest rate of diffusion, assuming all of the gases are at the same temperature? krypton argon helium O neon
What would happen to the value of the pressure if two changes were made 1 poi to the nitrogen gas, one after the other? First, the volume of the container is doubled (at constant temperature). Second, the temperature is doubled (with the volume no longer changing)? The amount of gas remains constant through both processes.A. The value of the pressure would double.B. The value of the pressure would be four times as great.C. The value of the pressure would be...
