Matthew 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?
density
magnetism
melting point
electrical conductivity
During a hot shower, water vapor fogs up the cooler mirror when it turns to water. This is an example of _____.
condenstation
evaporation
sublimation
deposition
In which state of matter are the particles likely to be closest together?
gas
liquid
plasma
solid
On which points on the graph is the water changing state?
F and G
G and K
F and H
F, G, H, and K
Match the following
Mass
Amount of matter in an object
Volume
Amount of space an object takes up
Weight
Force of gravity on an object
Density
Ratio: Mass divided by Volume
Students measure the mass of three objects on a pan balance and then measure their weight using a spring scale. They record their results in the table below.
What change would occur if the mass and weight of the objects were measured on the moon?
Mass and weight would remain consistent
Mass and weight would both change
Mass would not change, but weight would change
Mass would change, but weight would not change
The students in Ms. Ramirez's science class are classifying different types of reactions. They have divided the reactions into two columns as shown below. Use the table to answer
the questions that follow. Why are the reactions listed in Column A classified as chemical reactions?
They form new substances
They do not change the characteristics of the original substance
They change the shape of the substance
The products of the reaction can be changed back into the original products easily
Put the liquids in order from LEAST dense to MOST dense.
Oil
Water
Milk
Honey
A student is trying to separate a mixture of salt and pieces of iron.
Which method would be most useful for separating these two compounds?
Use a magnet on the sample
Mix the sample with water
Test to see if the sample is conductive
Find the volume and mass of the sample in order to find the density
The images below show the masses and compositions of six cubes. The cubes each have a volume of 1 cm3.
Which of the following has the greatest density?
silver
copper
aluminum
gold
A 6-cm3 cube with a mass of 63 g is made up of what substance?
iron
silver
aluminum
lead
A student measured a 4.5 cm3 piece of aluminum and calculated its density to be 2.7 g/cm3 . Based on the information given, is her calculation accurate?
No, because different-sized pieces of aluminum will have different densities.
No, because the volume of a sample of aluminum is not related to its density.
Yes, because experimental error can affect any experimental data.
Yes, because the density of aluminum doesn’t change based on the size of the sample.
Two groups of students were tested to compare their speed working math problems. Each group was given the same problems. One group used calculators and the other group computed without calculators. Match the variables for the experiment.
Dependent Variable
speed of working math problems
Controlled Variable
Same problems
Independent Variable
Use of calculators
Students mix two substances together. The starting materials are shown below.
After these substances are mixed, what would be the best way to separate the component parts?
Put the mixture on the stove, because the water will boil off, leaving the salt behind
Use a strong magnet, because the salt will be attracted to them but the water will not
Shake it through a series of fine mesh sieves, because the particle sizes are different
Place the beaker in a bowl of ice, because cooling the solution will cause the salt to melt away
If you could pick ONE person in this class to sit next to for our next unit who would it be?
