A student places four same-sized blocks (P, Q, R, and S) made of different materials in a beaker with water. The student observes what happens to each block and makes a list of conclusions. What conclusions are correct?

• 1 and 3

• 2 and 3

• 1 and 2

• 2 and 4

The second drawing shows a situation when a larger force is applied to the box than the force of friction. The result is that the box

• moves to the left

• moves right then left

• does not move

• moves to the right

The woman needs to make the box move faster. What can she do to make the box increase its speed in a forward direction?

• The woman can increase the mass of the box.

• The woman can apply a force on the box from the opposite direction.

• The woman can decrease the force on the box.

• The woman can apply a greater force on the box in the direction the box is moving.

A student predicts that water is denser than iron and cork. To test the prediction, the student pours 200 mL of water in a beaker and places a cork and an iron nail in the beaker. The image shows the student’s observations. Is the student’s prediction correct, and why?

• No. The iron nail sinks in water, indicating that iron is denser than water.

• No. The cork floats on water, indicating that cork is denser than water.

• Yes. The cork floats on water, indicating that water is denser than cork.

• Yes. The iron nail sinks in water, indicating that water is denser than iron.

A student places a 200 g chocolate bar in a pan, heats the pan, and observes that the bar melts. The student removes the pan from the heat and leaves the chocolate undisturbed to cool. After an hour, the student observes that the chocolate has become a hard solid with a mass of 200 g. How can the student classify this change?

• It is a reversible change because the mass of the chocolate is the same after cooling.

• It is an irreversible change because the shape of the chocolate changes.

• It is a reversible change because the chocolate returns to its solid state after cooling.

• It is an irreversible change because the solid chocolate changes into a liquid.

A student uses the setup shown to perform an experiment

The student observes that as marble chips are dissolved in the acid, bubbles start to form. The student also notices that the flask is warm to touch.

What evidence identifies the type of change taking place in the experiment?

• The rise in temperature indicates a chemical change.

• The dissolving marble chips indicate a physical change.

• The rise in temperature indicates a physical change.

• The change of phase of the marble chips indicates a chemical change.
