1. 10.0mL of ethanol at 25 °C
2. 10.0mL of ethanol at 55 °C
3. 100.0mL of ethanol at 35 °C
4. 100.0mL of ethanol at 45°C

Kinetic energy is directly proportional to temperature.
Hence the sample in which the temperature is the highest will have maximum kinetic energy
Therefore the correct answer will be 2.
