A balloon is left in the sun and heats up from 29.4°C to 33.7%. If the balloon was originally at 0.68L, what is the new volume of the balloon?

0.78L

Explanation:

According to Charles law, the equation below can be used to calculate the the new volume of the balloon

V1/T1 = V2/T2 eqn(1)

Where T1= initial temperature= 29.4°C

T,2= final temperature= 33.7°C

V2= final volume= ?

V1= initial volume= 0.68L

Making V2 the subject of formula from eqn(1)

V2=( T2 × V1)/T1

= (33.7 × 0.68)/29.4

=0.78L

Hence, the new volume of the balloon is 0.78L
