Melting, boiling and evaporation — practice question

The water in four beakers is at different temperatures, and the surface area of the water in each beaker is also different. In which beaker is the water evaporating at the fastest rate?

  • Atemperature $20\,\text{^{\circ}C}$; surface area $50\,\text{cm}^2$
  • Btemperature $20\,\text{^{\circ}C}$; surface area $100\,\text{cm}^2$
  • Ctemperature $25\,\text{^{\circ}C}$; surface area $50\,\text{cm}^2$
  • Dtemperature $25\,\text{^{\circ}C}$; surface area $100\,\text{cm}^2$
