#1: When you squeeze an airfilled balloon, what happens inside?
A. There are more collisions of air molecules against the wall of the balloon.
B. There are fewer collisions of air molecules against the wall of the balloon.
C. There is no change in the number of collisions of air molecules against the wall of the balloon.
D. The temperature inside the balloon decreases.
**my answer: A
is that right? not too sure haha @aaronq :)

Best ResponseYou've already chosen the best response.1#2: A pump contains 0.5 L of air at 203 kPa. You draw back on the piston of the pump, expanding the volume until the pressure reads 50.8 kPa. What is the new volume of air in the pump? A. 0.2 L B. 1.0 L C. 2.0 L D. 4.0 L **my answer: C. 2.0 L is that right? :/

Best ResponseYou've already chosen the best response.2yep, by squeezing the ballon you decrease the volume and increase the frequency of collisions since they're more "crowded"

Best ResponseYou've already chosen the best response.1#3: You place a balloon in a closed vacuum chamber at STP. You reduce the chamber pressure by half. What happens to the balloon? A. It reduces in size by half. B. It stays the same volume. C. It doubles in volume. D. It expands to four times the volume. **my answer: A is that right?

Best ResponseYou've already chosen the best response.23. is not correct. think about what happens if you reduce the pressure..

Best ResponseYou've already chosen the best response.1#5: This question appears on a quiz: "A 1.0 L balloon has a pressure of 2 atm. When the pressure increases to 1,000 kPa, what is the volume?" A student answers 0.002 L. Which of the following explanations is correct? A. The student did not solve for the correct parameter, and the answer should be 2.0 L. B. The student did not solve for the correct parameter, and the answer should be 0.5 L. C. The student did not put the pressures in the same units, and the answer should be 0.5.L. D. The student did not put the pressures in the same units, and the answer should be 0.2 L. ***my answer; D is that right?

Best ResponseYou've already chosen the best response.1kinda... i was debating between A and C for #3... but I'm not too sure haha :/ but if it isn't A, then is it C?

Best ResponseYou've already chosen the best response.2yep it's C, the balloon will expand because you're putting less pressure on it's walls
