The temperature of a spilled liquid has little or no impact on the spill's evaporation rate.

The temperature of a spilled liquid has little or no impact on the spill's evaporation rate.

• A. True
• B. False
• C. Uncertain
• D. Cannot be determined

Answer: (B)

The temperature of a spilled liquid is a major factor in how quickly it evaporates. When the liquid is warmer, its molecules have more kinetic energy, so more of them reach the surface with enough energy to break away into the air. This raises the vapor pressure at the surface and increases the rate at which the liquid turns into vapor. Conversely, cooling the spill slows evaporation. While other factors like surface area, air flow over the spill, and how volatile the liquid is also matter, temperature typically has a clear and significant effect. So the statement that temperature has little or no impact is not correct.
