The volume decreases to one-third of its original volume. C. The volume increases to three times its original volume. D. The temperature must also change for the volume to change. **my answer: B is that right?

#2 is correct #3 no idea
#4: You place a balloon in a closed chamber at standard temperature and pressure (STP). You double the chamber temperature while leaving the pressure constant. What happens to the balloon? A. It doubles in volume. B. It decreases to one-half of its original volume. C. It stays the same volume. D. It expands to four times its original volume. **my answer; A is that right?
okay! and lol alrighty :)
#5: You place air in a sealed can at standard temperature and pressure (STP). You heat it to four times its absolute temperature (K) while leaving the volume constant. What happens to the pressure?
