Mr. Fredrickson fills 1 million balloons to a volume of 2.5 liters each at sea level (1.00 atm), at 19 degrees Celsius. If the balloons carry his house to a height of 20,000 feet (0.77 atm), what is the temperature (Celsius) if they each shrink to a volume of 2.0 liters?

Answer : The temperature (Celsius) if they each shrink to a volume of 2.0 liters is,

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = 1.00 atm

= final pressure of gas = 0.77 atm

= initial volume of gas = 2.5 L

= final volume of gas = 2.0 L

= initial temperature of gas =

= final temperature of gas = ?

Now put all the given values in the above equation, we get:

Therefore, the temperature (Celsius) if they each shrink to a volume of 2.0 liters is,

i think it is true since you can test the answer and can use observations to complete it.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
