How hot will a 2.3 liter balloon have to get to expand to a volume of 7 L? Assume that the initial temperature of the balloon is 25 C?

Answer : The final temperature of balloon will be, 907 K

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

where,

are the initial volume and temperature of the gas.

are the final volume and temperature of the gas.

We are given:

Putting values in above equation, we get:

Therefore, the final temperature of balloon will be, 907 K

hey your not cool]      

the answer is true.
