Question

A cylinder witha movable piston contains an ideal gas. Both the amount of gas and the volume of the container can be adjusted, but the temperature remains constant at 300.0 K. Use the ideal gas law and the individual gas law relationships to answer the questi ons below. L x atm nRT where R = 0.08206 PV mol xK 1st attempt See Periodic Table See Hint Part 1 (1 point) Calculate the number of moles of the gas in the cylinder when the volume is set to 0.500 L and the pressure is 1.00 atm. mol (1 point) Part 2 What happens to the pressure of the gas when the amount of gas in the cylinder doubles and the volume is held constant? Choose one: A. It decreases by a factor of 2 B. It increases by a factor of 2 C. There is no way to tell D. There is no change in the pressure. (1 point) Part 3 What must happen to the volume in order for the pressure to return to 1.00 atm? Choose one: A. double its original value B. There is no way to return the pressure to 1 atm just by adjusting volume. C. Changing the temperature is the only way to affect pressure, and the temperature is fixed at 300 K D. half its origi nal value

Answer 1

PV = nRT na n RT 1.08 0.50 0.08218300 - 10.0203) may pan it increases by a factor by 2 (B) Pial P=2 (if moles is doubles half to As original valve
