Max is trying to classify a substance. The substance melts between the temperatures of 800°C and 1080°C. It has a hardness of about 2 -3 on the Mohs scale. The substance is also non-reactive with HCl (hydrochloric acid). What can be inferred about the substance?
It is likely a metal.
It is likely a non-metal.
It is likely an organic compound.
It is likely a gas.
Which element in the table comes closest to having the same properties as the substance that Max is trying to classify?
calcium
gold
lead
platinum
Which property of the rock is being measured when Amanda dropped it into a graduated cylinder containing water?
Mass
Volume
Density
Temperature
Using water displacement method (final volume - initial volume), identify the volume of the object.
5 mL
10 mL
35 mL
40 mL
An object placed in a container with 200 cm³ of water. What is the volume of water displaced?
50 cm³
40 cm³
30 cm³
20 cm³
Which of the following statements explains how objects with the same mass can have different densities?
The two objects have a different area.
The two objects have a different volume.
The two objects have a different color.
The two objects have a different temperature.
Which two containers should Max choose to investigate the effects that different temperatures have on the rate at which sugar dissolves?
A. 1 and 2
B. 1 and 3
C. 2 and 3
D. 2 and 4
If you take a triple beam balance from Earth to Mars to measure the mass of an object, will it show the correct mass of that object?
No, because the mass of an object depends upon gravity.
Yes, because the mass of an object remains the same regardless of the location.
Yes, because the balance measures the weight of the object which remains the same irrespective of the location.
No, because the balance is calibrated to measure the mass of an object on Earth that has different gravity than Mars.
Which property is used to classify and compare substances?
Color
Density
Taste
Shape
If you found an unknown clear liquid in the laboratory, which of these physical properties would be most helpful to identify the type of liquid?
its color
its mass
its volume
its boiling point
What is the most reliable method to determine the density of an irregularly shaped object?
Submerge it in water and measure the displaced volume.
Estimate its size by visual inspection.
Use a colorimeter to assess its color.
Measure its mass and calculate its volume using a ruler.
Which of the following properties is not typically used to identify a substance?
Electrical conductivity
Shape
Boiling point
Melting point
When comparing two substances, which property would be most useful to determine if they are the same?
Mass
Color
Density
Volume
Which box has a higher density?
A
B
They are the same
What is the difference between mass and weight?
Mass is measured in liters, while weight is measured in grams.
Mass is the amount of matter in an object, while weight is the force of gravity on an object.
There is no difference; they mean the same thing.
Weight can only be measured on Earth, mass can be measured anywhere.
