Properties of matter

A student was asked to compare the masses of four blocks that were all the same size but made of different materials. The student used a balance to compare the masses of two blocks at a time. The student repeated this process three more times with different pairs of blocks and recorded observations.

Which list shows the blocks in order from least to greatest mass?

• Blocks N, M, L, P

• Blocks P, M, L, N

• Blocks N, L, M, P

• Blocks P, L, M, N

Students are conducting an investigation with breakfast cereal. The first four steps of the investigation are shown in the table below.

Breakfast Cereal Investigation:

1. Grind 50 grams of cereal into a fine powder

2. Stir the cereal powder into 500 milliliters of warm water.

3. Hold a magnet against the side of the beaker at the 250-mililter mark.

4. Slowly move the magnet around the beaker keeping it touching the surface of the beaker.

 

Which of the materials below can be identified using the procedures of this investigation?

• A. sugar

• B. salt

• C. iron

• D. wheat

3.  For an investigation, a teacher dropped a bolt into a container of maple syrup and asked students to remove it without touching the syrup. The students first tried to use a strong magnet to remove the bolt,
but it remained at the bottom of the container. They finally poured the syrup into a container to get the bolt out.

• The bolt is magnetic and has the same density as the maple syrup.

   

• The bolt is not magnetic and more dense than the maple syrup.

• The bolt is not magnetic and less dense than the maple syrup.

   

• The bolt is magnetic and less dense than the maple syrup.
