A) 9.95 L
B) 0 L
C) 4.22 L
D) 74.1 L
E) 7.71 L

The volume of a gas is directly proportional to its temperature in Kelvin. To find the new volume, convert temperatures to Kelvin (37°C = 310K and 0°C = 273K) and use the formula V1/T1 = V2/T2. Solving for V2 gives V2 = V1 * (T2/T1) = 8.76L * (273K/310K) = 7.71L.
