In which of the following will water evaporate earlier?

Correct answer: B. Saucepan

  • A. Cup
  • B. Saucepan
  • C. Glass
  • D. Small bowl

Explanation

The rate of water evaporation depends on various factors such as the surface area exposed to air, temperature, humidity, and airflow. In general, water will evaporate more quickly in conditions where these factors promote evaporation. If we assume that the initial conditions (temperature, humidity, etc.) are the same for all containers, then the primary factor influencing the rate of evaporation would be the surface area exposed to air. Larger surface areas allow for more water molecules to be in contact with the air, promoting faster evaporation. A wide saucepan typically has a larger surface area compared to a cup, glass, or small bowl. Therefore, under similar conditions, water is likely to evaporate earlier from a saucepan than from the other containers.
