The gas in a balloon occupies 2.25 L at 298 K at what temperature will the balloon expand to 3.50 L

The temperature that the balloon will expand to 3.50 l is 463.56 K

calculation

by use of Charles law formula

that is V1/T1 = V2/T2 where;

V1 = 2.25 l

T1 = 298 k

V2 = 3.50 l

T2=?

make T2 the subject of the formula T2 = (V2 xT1) / v1

T2 = (3.50 l x 298 K) / 2.25 L = 463.56 K
