<span>It is true that energy efficient dishwasher is a water
and energy saver than washing dishes by hand. A star-rated dishwasher uses 4
gallons of water in each cycle compare to a kitchen faucets who pumps out 2.5
gallons of water per minute. To conserve water, the accumulated dishes and cookware
must be stack properly in a dishwasher before running a cycle. As to conservation
of energy, people tend to use warm water to wash the dishes by hand and heating
of water cost much, while in a dishwasher, energy-saving tips such as running a
light cycle and turning off heating drying option will mark down your energy
consumption. Therefore, the use of dishwasher is a much greener idea. </span>
Answer: all other conditions equal, the rate evaporation of a contained liquid will be slower than the rate of evaporation of an uncontained liquid.
Justification:
1) The rate of evaporation increases as the surface area of the liquid (relative to the whole content) increases. This is, the greater the surface is the faster the evaporation.
2) That is so because the higher the surface of the liquid the more the number of particles in the liquid that are in contact with the surrounding air and so the more the particles will escape from the liquid to the air (which is what evaporation is).
3) A liquid contained will take the form of the container, so part of the liquid wil remain below the surface, while an uncontained liquid will spread all over the surface and so pratically all the liquid is in contact witht the air surrounding it.
