⚡️ FROM THE ABOVE QUESTION IT'S CLEAR THAT IT IS A NUMERICAL FROM CHARLE'S LAW ⚡️

⭐️ Initial Volume (V1) = 80 cm³
⭐️ Final Volume (V2) =
$80 + 80 \times \frac{20}{100} {cm}^{3}$
= (80 + 16) cm³
= 96 cm³

⭐️ Initial temperature (T1) = 25℃
⭐️ Final temperature (T2) = ?

ACCORDING TO CHARLE'S LAW :

$V1/T1 = V2/T2$
$=> 80/25 = 90/T2$
$=> 3.2 = 90/T2$
$=> T2 = 28.12 °C$
