GIVEN :
• Volume (V1) = 40ml
,• Temperature (T1)= 20° C
,• Temperature (T2) = 40°C
,• Volume (V2) = ?
We will apply Charles law formula : that states that volume is directly proportional to its absolute temperature, if the pressure remains constant
[tex]\frac{V_1}{T_1}=\text{ }\frac{V_2}{T_2}[/tex]Substituting the given parameters into the above formula, we get that V2 =
[tex]\begin{gathered} V_2=\frac{V_1*\text{ T}_2}{T_1} \\ \text{ =}\frac{40\text{ mL * 40 }\degree C}{20\degree C\text{ }} \\ \therefore V_2=\text{ 80 mL } \end{gathered}[/tex]
