Question

22. Pressure is created when a gas is compressed and the temperature is decreased proportionally b) gas particles collide with the sides of their container more gas particles are added and the volume is increased proportionally gas particles are removed and the volume stays the same 23. because In response to Boyle's law, the pressure of a gas increases as the volume a) decreases; the gas particles strike the walls of the container more often increases; the kinetic energy of the gas particles increases decreases; the kinetic energy of the gas particles decreases increases; the gas particles strike the walls of the container more often d) 24. If the amount of a gas is tripled and the volume of the container is also tripled the new pressure of the gas will: a) be equal to the original pressure b) be six times the original pressure c) be nine times the original pressure d) be 1/6th of the original pressure 25. You're at the zoo and have a big red 3.20 L helium balloon. The barometric pressure is 790.0 mm Hg. Then you hear the roar of a lion. Startled, you accidently release the balloon. It flies away. By the time it reaches the clouds the atmospheric pressure is only 0.300 atm. What is the new volume of the balloon? a) 6.20 L b) 11.11 C) 1.06L d ) 8.43 L

Please answer & explain 22-25

Answer 1

Question 22

Correct answer is (b), due to collision with the wall of the container, pressure is created,

Rest of the option does not cause any change in the pressure.

Question 23

(a) decreases because gas particles strike the wall more often.

During Boyle's law, temperatures is constant, thus kinetic energy will be constant hence b, c are incorrect

Question 24

(a) no change in the pressure, because Amount and volume is proportionally increased

Question 25

Assuming temperature as constant,

P1V1 = P2V2

P2 = 0.3 atm = 0.3 ×760 = 228

V2 = (3.2×790) /228 = 11.1 L
