Final answer:
To find the missing volume (V2) using Charles's law, we need to set up an equation and solve for V2. The equation is V₁/T₁ = V₂/T₂, where V₁ and T₁ are the initial values and V₂ and T₂ are the unknowns. By substituting the given values and solving, we find that V₂ = 89.6 mL.
Step-by-step explanation:
Given: V₁ = 80.0 mL, T₁ = 27°C, T₂ = 77°C, V₂ = ?
Charles's law relates the volume of a gas to its temperature. It states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. The formula for Charles's law is V₁/T₁ = V₂/T₂, where V₁ and T₁ are the initial volume and temperature, and V₂ and T₂ are the final volume and temperature.
Using the given values, we can set up the equation as follows:
80.0 mL / (273 + 27) K = V₂ / (273 + 77) K
Solving for V₂ gives:
V₂ = (80.0 mL / (273 + 27) K) * (273 + 77) K
V₂ = 89.6 mL
