Which evaporates more quickly: 55 mL of water in a beaker with a diameter of 4.5 cm or 55 mL of water in a dish with a diameter of 12 cm, and is the vapor pressure of the water different in the two containers? Explain.

<Step 1: Understand the concept of evaporation. Evaporation is the process where molecules at the surface of a liquid gain enough energy to enter the gaseous phase.>
<Step 2: Consider the surface area of the liquid. The rate of evaporation is directly proportional to the surface area exposed to air.>
<Step 3: Compare the surface areas of the two containers. Calculate the surface area of the water in each container using the formula for the area of a circle, A = \pi r^2, where r is the radius.>
<Step 4: Analyze the relationship between surface area and evaporation rate. The container with the larger surface area will have a higher rate of evaporation.>
<Step 5: Discuss vapor pressure. Vapor pressure is a property of the liquid itself and is not affected by the shape or size of the container, so it remains the same in both containers.>
