  1. A gas has a volume of 5 liters at 25 degrees C (25⁰ C). Find the final temperature of the gas if the volume doubles to 10 liters. Show both the equation you used to get your answer as well as your work. Also, why or why not your answer makes physical sense based on what you have learned in class.
  2. A weather balloon has a volume of 1800 liters at 103 kPa (kilo Pascals). The balloon is released into the atmosphere. When it reaches its highest point above the ground, the pressure on the balloon 30 kPa. What is the balloon’s new volume at this height? Show both the equation you used to get your answer as well as your work. Also, why or why not your answer makes physical sense based on what you have learned in class.  
  3. On a perfect fall day, you are hovering at low altitude in a hot-air balloon, accelerated neither upward nor downward. The total weight of the balloon, including its load and the hot air in it, is 20,000 N. The density of air is about 1.2 kg/m3. Show your work and explain your reasoning.
  1. Find the volume of the displaced air.

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...

a) A mildly restored ‘Knight-Rider’ 1989 Pontiac Trans Am GTA powered by a 5.7 litre V8 can do a quarter mile S from rest in a time t of about 15 seconds. Using distance: S=a t2 /2 , force: F=ma and work: W=FS, calculate the amount of work (energy) in kJ required to do the standing quarter mile given that the mass (m) of this Trans Am is 3,500 pounds. Assume that the acceleration (a) is constant. (This is not...
