physics help please?
1. A man fills a balloon with .5 liters of air. He then puts the balloon into the oven and heats it to 204•C. The temperature outside the oven was 20•C.
- 1A - what is the new volume of the balloon?
- 1B - what gas law is used to solve this?
2. A hot air balloon descends from a pressure of 380 mm Hg to 760 mm Hg and at the high altitude has a volume of 1,000 cubic meters. The initial temperature is 50•C and drops to 25•C.
-2A - convert Celsius temperature to kelvin ( absolute temperature). what are the new temperatures?
- 2B - what would be the final hot air ballon volume?
- 2C - which has law should be used determine the unknown (the final volume)?
