Selected Response Item

Seawater contains a number of different salts. The water can be separated by a process called distillation. A simple distillation setup is shown below.

Question Image

The water in the flask evaporates. Water vapor (gas) rises, leaving the salt in the flask. The water vapor is cooled in the condensing tube and drips into the beaker.

Why does salt remain in the flask?

  1. Salt is attracted to heat.
  2. Salt does not evaporate.
  3. Salt is too heavy to become a vapor (gas).
  4. Salt becomes water after it is heated.

Selected Response Item

Use the information below to answer the following:

Students placed 250 milliliters of water in three identical containers. Container 1 had a tightly sealed lid and was placed on a classroom counter. Container 2 had no lid and was placed on a classroom table. Container 3 had no lid and was placed on a table outside in the shade. The students measured the amount of water in each container at the end of each day for four days. Their results are shown in the data table below.

VOLUME OF WATER IN THREE CONTAINERS

Container Starting Volume (mL) End of Day 1 (mL) End of Day 2 (mL) End of Day 3 (mL) End of Day 4 (mL)
1 250 250 250 250 248
2 250 242 219 203 188
3 250 219 172 125 63

What question is this investigation designed to answer?

  1. How do water levels affect evaporation?
  2. Which container best holds evaporating water?
  3. Does evaporation of water affect the atmosphere?
  4. In which environment does water evaporate the fastest?
