Physical Science Eoc Review

Arguments can be made for using fusion rather than fission as an alternative energy source. What would be one advantage of fusion reactors?

• Fusion reactors would have a longer lifetime.

• It would be easy to build a fusion reactor.

• Fusion reactors would produce no radioactive waste.

• A fusion reaction would be easier to control.

A student moved a sample of matter from a small container to a larger container. The matter changed shape and did not fill the container completely. What was the phase of the matter?

• solid

• liquid

• gas

• plasma

A student investigated gases by filling a balloon to its maximum capacity inside his air-conditioned home. He then walked outside into the intense summer heat. What could happen to the balloon?

• It could pop because the increase in temperature would cause an increase in volume.

• It could pop because the increase in temperature would cause a decrease in pressure.

• It could get smaller because the increase in temperature would cause a decrease in pressure.

• It could get smaller because the increase in temperature would cause a decrease in volume.

Four solutions are prepared in beakers. In all solutions, 20 g of sugar are added to 100 mL of water. Beaker A is placed on the lab table at room temperature (25°C). Beaker B is placed in the refrigerator. Beaker C is placed on a hot plate set at 40°C. In what order would the beakers be arranged to show the dissolving of sugar from fastest ro slowest?

• A, B, C

• B, A, C

• C, A, B

• C, B, A

A student used a timer to find out how quickly sugar dissolved in water with and without stirring. Which is the BEST prediction of the student's results?

• Dissolving will occur at the same rate with and without stirring.

• Stirring will change the concentration of the sugar solution that will form.

• Sugar will dissolve faster when it is stirred than when it is not stirred.

• Stirring will change the final conductivity of the sugar solution that will form.

A student has made a model of a solution by drawing a diagram. She wants to label the solvent and solute. Which BEST explains how she could determine which substance is the solute in her model?

• The solute is always a liquid.

• The solute is the material that dissolves.

• The solute can be either of the substances in a solution.

• The material present in the greatest amount is the solute.

A car burns gasoline to move. What types of energy is found in the gasoline, and what types of energy is it ultimately transformed into?
