The diagram above shows one container with oil and water and another with oil and a cork. Which diagram below shows what most likely would happen if oil, water, and the cork were all put in the same container?
Which of the following is a good conductor of electricity?
glass rod
cotton string
plastic tubing
copper penny
A teacher mixes a white powder into a beaker of water. The powder cannot be seen in the water. The teacher then heats up the water until it evaporates and the powder can be seen again. Which of the property of the powder is the teacher demonstrating?
solubility
Density
Conductivity
Mass
5 Jars with 92* C water are set up with thermometers. 4 jars are wrapped equally with different material. One jar is kept unwrapped as a control. After 10 minutes the temperature is checked and noted in the above chart. Which property of the material is most likely being tested?
state of matter
Thermal energy insulation
Thermal energy production
ability to conduct electricity
A student reads the label on the salad dressing above. Why would the students shake the salad dressing well before using it?
Vinegar and oil have different densities
Vinegar and oil easily form a solution
Vinegar and oil both contain water
Vinegar and oil are both liquids
What is the difference in grams between the total mass of the liquid substances and the total mass of the solid substances in the above chart?
298
130
168
428
A teacher wears protective gloves to lift a metal pan filled with boiling water from a hot plate. Why are the protective gloves necessary?
The metal pan creates thermal energy.
the metal pan insulates thermal energy.
The metal pan conducts thermal energy.
The metal pan reduces thermal energy.
Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. The objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of the objects?
The keys and coins are less dense than water, so they can easily picked off the bottom of the pool by divers.
The foam cups have the same density as water, so they can be crumbled up for removal by the pool filter
The foam cups are less dense than water, so they can be removed from the surface with a pool cleaning net.
The keys and coins have the same density as water, so they can be washed away when the pool is drained.
A cook uses the ingredients listed above. Which table below shows the physical properties of these ingredients when placed in hot water?
A teacher gives a student 4 clear sealed containers. Each container holds a different substance. The students record their observations about each substance. Based on these observations, which container most likely holds only gas?
Container 1
Container 2
Container 3
Container 4
Some students investigate the properties of matter of four objects using a hand lens, a magnet, and a beaker containing water. Their observations are recorded on the table. Which statement identifies a property that could be used to classify these objects into two different groups?
Density can be used to separate objects that sink in water from objects that don't.
Magnetism can be used to separate objects that are attracted to magnets from objects that are not.
Solubility can be used to separate objects that dissolve in water from objects that do not.
Physical state can be used to separate objects that are solid from objects that are not.
A student classifies the above objects shown based on their physical properties. Which property cannot be used to classify these objects into more than one group?
Magnatism
Mass
Electrical Conductivity
Solubility in water
A science class tested 3 properties of different materials. The results are shown in the table above. Based on the table, which material would be best to use to insulate electrical wire?
wood
plastic
copper
steel
Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep them from starting a fire. Why does the plastic keep the electricity from starting the fire?
Plastic is a good insulator
Plastic can melt when heated
Plastic is softer that wire
Plastic conducts electricity
A student has puts 4 objects in a bucket filled with water. The objects are listed above. Which two objects are most likely less dense than water?
Wood block and metal paper clip
plastic ball and glass marble
metal paper clip and glass marble
wood block and plastic ball
A student compared the mass of 4 blocks of the same size but different material. He used a balance to compare the masses of two blocks at a time. He repeated this process 3 times with different pair of blocks and recorded observations. Which list shows the blocks in order from least to greatest?
Blocks in N, M, L, P
Blocks in P, M, L, N
Blocks in N, L, M, P
Blocks in P, L, M, N.
The table lists some properties of 4 different samples of matter. Which two samples could be glass and saltwater?
Sample 1 and 2
Sample 3 and 4
Sample 1 and 3
Sample 2 and 3
Which of these is NOT soluble in water?
oil
salt
honey
sugar
A student is asked to design a sleeve for a cup that will insulate thermal energy and not feel hot to the touch when the cup is filled with liquid. The students has 4 materials to choose from. Which of these materials is least useful as an insulator?
cardboard
aluminum
rubber
plastic
A teacher dropped a bolt into a container of maple syrup and asked the students to remove it without touching the maple syrup. At first they used a strong magnet but the bolt would not move. They finally poured the maple syrup into another container to get the bolt out. Which of these best describes some of the bolt's properties?
The bolt is magnetic and has the same density as the syrup
The bolt is nonmagnetic and more dense than the maple syrup
The bolt is nonmagnetic and less dense than the syrup
The bolt is magnetic and less dense than the maple syrup
