B) 3.69 L
C) 4.34 L
D) 8.00 L

The volume of a gas is directly proportional to its temperature in Kelvin when pressure is constant (Charles's Law). To find the new volume, convert temperatures to Kelvin (25°C = 298K, 50°C = 323K) and use the formula V1/T1 = V2/T2. Solving for V2 gives V2 = V1 * (T2/T1) = 4.00 L * (323K / 298K) = 4.34 L.
