CA1 Physical Properties of Matter

Kai fills a beaker with 200 mL of water. He measures the mass of the beaker and water to get 230 g. He collects 50 g of salt. Kai adds the salt to the water and stirs. Next, Kai measures the mass of the solution he has made. When Kai measures the mass of the beaker with the solution, what is the mass?

• 200 mL

• 230 g

• 50 g

• 280 g

Look at the image of the pot. Cara is identifying the physical properties of this item. Pick the words, in order, that best complete the paragraph. Cara investigated this item by placing it on a digital scale to determine its _______. She runs her hand over the surface and determines that the _______ is smooth. She can tell by observation that it is a solid, and it is used to heat food.

• mass; color

• weight; hardness

• mass; texture

• weight; mass

A class is studying the ability of substances to float and sink. Each study group is given 3 beakers, 3 substances, and a quantity of water. Which sentences state what Lucia’s group found out? Choose all that apply.

• Aluminum is more dense than water.

• Cork and wood have the same density.

• Wood is more dense than aluminum.

• Cork, because it floats on top of water, is the least dense.

Part B: How can Elena separate the sand and water?

• By pouring off the water into a different bowl

• By evaporating the water from the sand by applying heat

• By passing the sand and water through a sieve

• By using a magnet to separate the substances

A company is producing a new set of baking pans. They consider several materials with different properties to use for the baking pans. The company wants to use a material with high thermal conductivity. The company will combine aluminum with another metal to make the pans. Which combination will have the best thermal conductivity?

• Aluminum and brass

• Aluminum and copper

• Aluminum and iron

• Aluminum and stainless steel

Look at the illustration of the magnets. Because the construction project she is designing will be exposed to high levels of magnetism, Monique wants to find the best product to use in building the cabinets in the laboratory. Which of these would explain what Monique is doing to find this building material? Choose all that apply.

• Monique tests three types of screws with a magnet to find one that is not magnetic.

• The steel screws would probably work on this project because they are stronger than iron or aluminum.

• Screws would not be affected by the magnetism in the room, so all the screws would work.

• The aluminum screws are the best to use because they do not react to magnetism.

Read the passage and use the image to answer the next two questions. A class is studying states of matter. Each student is given this illustration. Students are asked to determine what the illustration represents and how it would apply to their investigations. Jenna's group is given a list of five items. They are asked to determine which items on the list are represented by illustration A. Help Jenna’s group by selecting all the listed items that are the same state of matter as illustration A.

• An apple

• Grape juice
• Helium in a balloon

• A pencil

• Pancake batter

Zach’s group is supposed to compare and contrast a rock, a small wooden block, and a 2.5 cm × 2.5 cm × 2 cm block of steel. Each person will measure the mass of each item. The group determines that these are the steps to follow to compare and contrast the mass of these substances, though not necessarily in the correct order. 1. Compare the data in the table for each item to check that all group members measured accurately. 2. Collect the materials and get a balance and various gram weights. 3. Make a table of the data collected by each student. 4. Measure the mass of each substance on the balance. 5. Record the mass of each substance as it is measured. In which order should Zach’s group complete the steps?

• A. 2, 4, 5, 3, 1

• B. 1, 2, 4, 5, 3

• C. 4, 3, 4, 2, 1

• D. 3, 2, 1, 4, 5

When people first began to put electric wiring in their homes, they were concerned that electrical energy might start a fire. To avoid this problem, copper wires were coated with rubber. Which sentence explains the physical properties that made the coated wiring safe?

• Both the copper and the rubber are good insulators for preventing electrical energy from flowing out of a wire and causing a fire.

• The copper is a good conductor of electrical energy, but the rubber stops the electrical energy from flowing outside the wire.

• The copper is an excellent insulator, and the rubber is an excellent conductor, so they combine to make safe wiring.

• Neither the copper nor the rubber can conduct electrical energy, so the rubber-coated wiring was safe to use.

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight
