- 1. Multiple ChoiceWeight is proportional to but not equal to mass. In which of the following situations would a person show an increase in weight but not an increase in mass?Climbing to the top of a mountainTraveling underwater in a submarine.Landing on a planet with more gravity.Living on the international space station.
- 2. Multiple ChoiceKendall has 4 beakers, each containing 10 milliliters (mL) of a different liquid. He finds the mass, in grams (g), of each liquid and records it in his notebook. His data are shown in the table. Kendall wants to know what will happen when the liquids are all combined. He pours them all into a 50-mL beaker, and after a few minutes, the liquids separate into different layers. Which liquid would make up the bottom layer of the beaker?Vegetable oil, because it has the least amount of mass. Karo syrup, because it has the greatest density.. Water, because it sinks into all substances.Milk, because it contains fat.
- 3. Multiple ChoiceTim is helping his mom make a dessert. Tim measures out one gram of peanuts and one gram of marshmallows. Which of these will need the largest container?They will need the same size container because there is one gram of each.The peanuts will need a larger container because they are irregularly shaped.The peanuts will need a larger container because a peanut is heavier than a marshmallow.The marshmallows will need a larger container because they are less dense.
- 4. Multiple ChoiceJan noticed that when she put a tomato in water, it sank. When she put an apple in water, it floated. Why did the tomato sink while the apple floated?The apple has more surface area than the tomato, which allowed the apple to float.The apple is denser than the water, and the tomato is less dense than the water.The tomato is denser than the water, and the apple is less dense than the water.The apple and the tomato have the same density, but the tomato skin absorbed water, making it sink.
- 5. Multiple ChoiceMatthew has six cubes of different materials. Each cube has a mass of 10 grams (g). Matthew sorts the cubes into two groups using one physical property. Which physical property did Matthew most likely use to sort the cubes into two groups?densitymagnetismmelting pointelectrical conductivity
- 6. Multiple ChoicePhysical properties can be used to classify and compare substances. The illustration below shows a physical property that is being investigated using different materials. What physical property is most likely being investigated in this illustration?magnetismmelting pointelectrical conductivitythermal conductivity
- 7. Multiple ChoiceThe state of matter is an example of a physical property. Why is the state of matter considered a physical property, even though a substance may change between a solid, liquid, and gas?The property can be easily observed.The chemical nature of the substance does not change.The state of matter depends on the amount of substance present.Solids, liquids, and gases contain different substances from one another.
- 8. Multiple ChoicePhysical properties can be used to compare and classify substances. The process below demonstrates a physical property of sugar. Which of the following physical properties of sugar is demonstrated by the process?thermal conductivitymelting pointSolubilitydensity
- 9. Multiple ChoiceA pebble is dropped into a cup of water and sinks to the bottom of the cup. A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare?They both have the same mass.They are both denser than water.They both have the same density.They both contain the same material.
- 10. Multiple ChoiceSarah is completing a lab in which she is required to identify an unknown substance. She records several observations and measurements of the substance. Which of the following properties will be most helpful to Sarah in making a correct identification?densitymassvolumeweight
- 11. Multiple ChoiceWhich of the following best explains why silicon dioxide is a solid at room temperature, but water is a liquid?Silicon dioxide is soluble in water.Water has a higher density than silicon dioxide.Silicon dioxide has a higher melting point than water.Water conducts electricity, but silicon dioxide does not.
- 12. Multiple ChoiceDaryl is conducting experiments on samples of pure copper (Cu). While collecting data, he records both physical and chemical properties of the metal. Which of the following is dependent on the amount of Cu in the sample?electrical conductivitydensitymassmelting point
- 13. Multiple Choice) Katie's teacher has given her a sample that contains a mixture of salt, sand, and iron filings. She is instructed to separate the mixture into the three individual components. What would be the best physical property to focus on for the first step in separating the mixture?densityelectrical conductivitymagnetismmelting point
- 14. Multiple ChoiceAmanda is presented with a piece of metal and asked to determine its physical properties. Which of the following groups best represent the physical properties of metal.thermal conductivity, magnetism, low melting pointsoluble in water, thermal conductivity, low melting pointmagnetism, electrical conductivity, high melting pointelectrical conductivity, high melting point, soluble in water
- 15. Multiple ChoiceThomas performed an experiment to measure the temperature of water as he heated it on a hotplate. At the end of his experiment, he plotted the results as shown in the graph. Which of the following physical properties of water did Thomas measure?melting point and boiling pointvolume and thermal conductivitysolubility and electrical conductivitydensity and physical states of matter
- 16. Multiple ChoiceA jeweler has two blocks of gold. The first block has a mass of 60 grams (g) and a volume of 3 cubic centimeters (cm3). The second block has half the mass and half the volume of the first block. What is the density of the smaller block of gold, in grams per cubic centimeter (g/cm3)?5 g/cm310 g/cm320 g/cm380 g/cm3
- 17. Multiple ChoiceKari likes to play marbles, and she wants to find out if the density of a marble has any effect on how far the marble rolls. To begin, she selects ten different marbles of various sizes from her collection. She measures the first marble on a balance and finds that its mass is 13.8 grams (g). Then she takes a 100-milliliter (mL) graduated cylinder and fills it to the 50-mL mark. After she places the marble in the graduated cylinder, the water level reads 56 mL. What is the density of this marble, in grams per milliliter (g/mL)?0. 25 g/mL0. 43 g/mL2. 3 g/mL4. 1 g/mL
- 18. Multiple ChoiceThe terms mass and weight are often used interchangeably. When you purchase produce from the grocery store, you place your items on a spring scale. What physical property of matter is being measured?MassWeightMass and WeightThe amount of material in an object
- 19. Multiple ChoiceIn 1969, Neil Armstrong became the first person to walk on the Moon. Video coverage showing the astronaut walking on the surface of the Moon gives the impression that he was bouncing while he walked. What is the reason for this?The astronaut's mass on the Moon decreases.The density of the astronaut on the Moon is higher than on Earth.The atmosphere of the Moon affects the way the astronaut is able to move.The astronaut's weight on the Moon depends on the Moon's gravitational force.
- 20. Multiple ChoiceWhen two liquids are poured into a graduated cylinder, two-layers form. Liquid A has a volume of 16 ml and a mass of 87 g. Liquid B has a volume of 234 ml and a mass of 100 g. Based on this information which liquid will form the top layer? Density = Mass /VolumeLiquids A and B have equal densities, so there will be no layers.Liquid B because its density is greater than liquid A.
Liquid B because it is less dense than liquid A.Liquid A because it is less dense than liquid B.
