A balloon has a volume of 2.00 liters at STP. What will happen to the balloon's volume if it is moved to an elevation where the pressure is the same and the
temperature is much cooler?

Help pass my final

The volume of the ballon decreases as much as the temperature is much cooler.

Explanation:

In the problem, the pressure remains constant whereas the temperature decreases. Charles's law states that the temperature is directly proportional to the volume under constant volume.

As in the problem the pressure remains constant but the temperature decreases:

The volume of the ballon decreases as much as the temperature is much cooler.

the answer is 0.8m.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
