Will the volume of a gas decrease, increase, or remain unchanged for each of the following sets of changes? a) The pressure decreased from 4 atm to 1520 mm Hg, while the temperature is decreased from 250°C to 212°F. b) The pressure is increased from 450 torr to 2280 mm Hg, while the temperature is increased from 212°F to 150°C. Please explain this question in detail to me because i am really lost Please do not answer if you are just going to answer the question if you are going to post a retarded answer on how i should learn thing ...because i am trying to learn how to do this and i have been trying to work it out all night. And my teacher made this an open class question not a homework question but i need to learn this for a test.
