QUESTION:
An ideal gas originally at 0.85 atm and \(66^{\circ} \mathrm{C}\) was allowed to expand until its final volume, pressure, and temperature were 94 mL, 0.60 atm, and \(45^{\circ} \mathrm{C}\), respectively. What was its initial volume?
ANSWER:Step 1 of 2
The goal of the problem is to calculate the initial volume of the gas.
Given:
\(P_1\) = 0.85 atm
\(T_1\) = 66°C = 66 + 273 = 339 K
\(P_2\) = 0.60 atm
\(T_2\) = 45°C = 45 + 273 = 318 K
\(V_2\) = 94 mL
\(V_1\) = ?
