Aballoon filled with helium has a volume of 4.6 x 103 l at 31°c. what volume will the balloon occupy at 56°c if the pressure surrounding the balloon remains constant? be sure to answer all parts. enter your answer in scientific notation. x 10 (select) ^l

5x10^3 L

Explanation:

Charle's Law states that the volume of a fixed amount of gas maintained at constant pressure is directly proportional to the absolute temperature of the gas, for a constant amount of gas we can write:

As the pressure of the balloon doesn't change, we can use Charle's Law to solve the problem. Firs we change the given temperatures to absolute temperature units ( °K), using the following relations:

°K=273,15+°C

Therefore:

V1=4.6 x 10^3 L, T1=273,15+31=304,15°K

V2=?,                   T2=273,15+56=329,15°K

The new volume of the balloon is 5x10^3 L.

what is the question here. i think you messed up.
