A student filled each of four beakers with 100 ml of water at 25 degrees celsius. The student added an equal amount of different substances to each of the beakers of water. Based on the student's observations in the table, how many of the substances did NOT dissolve in the water? (TEKS 5.5A 2019-Q22)

A student wants to classify four different objects based on physical properties. The student uses the questions shown in the table to test ech object. Which statement correctly identifies two of the materials based on the classification of properties in the table? (TEKS 5.5A 2019-Q30)

• Material 1 is a rubber ball.

  Material 2 is a piece of cardboard.

• Material 2 is an aluminum washer.

  Material 3 is a copper wire.

• Material 3 is a piece of cardboard. Material 4 is an aluminum washer.

• Material 1 is a copper wire. Material 4 is a rubber bll.

The table list some physical properties of two objects. Based on their properties, which of the objects is most likely a metal? (TEKS 5.5A 2018-Q5)

• Object 1, because it is a solid that is less dense than water.

• Object 2, because all metals float in water.

• Object 2, because metals conduct thermal energy and electricity.

• Object 1, because it can be used to provide insulation for thermal energy.

Design a project to compare the effects of physical changes (such as temperature and pressure) on different states of matter.

• Heat and cool water, ice, and steam to observe changes in state and record temperatures at which these changes occur.

• Freeze and melt different metals to see which one has the highest melting point.

• Apply pressure to various solids to determine their hardness.

• Observe the color changes in substances when heated without measuring temperature.
