Standard 4.0 Chemistry

Topic D. Physical and Chemical Changes

Indicator 1. Provide evidence to illustrate that when a new material is made by combining two or more materials, its properties are different from the original materials.

Objective a. Investigate and describe what happens to the properties of materials when several materials are combined to make a mixture, such as table salt and pepper; various kinds of nuts, chocolate pieces, and coconut; sugar dissolved in milk

Selected Response Item

Science students observed the physical properties of different materials. They recorded their observations in the data table below.

Correct Answer:
C

Selected Response Item

Use the information below to answer the following.

A teacher conducted an investigation that demonstrated changes in matter. Three beakers were used in the investigation. Each empty beaker had a mass of 400 grams. Beaker W and Beaker X each contained 25 grams of sugar. Beaker Z contained 500 milliliters of water at 60° Celsius.

The teacher poured the sugar from Beaker W into Beaker Z. The teacher stirred the sugar and water until the sugar was not visible.

Next, the teacher slowly heated the sugar in Beaker X on a hot plate. Within a few minutes, the sugar melted. The melted sugar turned brown and began to smoke. Finally, the melted sugar turned black and became a solid.

What property of the water most likely changed after the teacher added the sugar?

  1. color
  2. flavor
  3. hardness
  4. odor
