Answer:
New Gas volume (V2) = 5.86 L
Explanation:
Given:
Gas volume (V1) = 2.93 L
Temperature (T1) = 20°Celsius
After Increasing temperature:
New Temperature (T2) = 40°Celsius
Find:
New Gas volume (V2) = ?
Computation:
According to Charles' gas Law:
⇒ Gas volume (V1) / Temperature (T1) = New Gas volume (V2) / New Temperature (T2)
⇒ 2.93 L / 20°Celsius = New Gas volume (V2) / 40°Celsius
⇒ New Gas volume (V2) = 5.86 L
