Let's get Physical
100
The state of matter with particles that are close together and vibrate slowly in place.
What is a solid?
100
The equation and units for density
What is d = m ÷ v and g/cm3 or g/mL

Aluminum has a mass of 27 g and a volume of 10 cm3. Calculate the density and include the units. Hint: d = m ÷ v
What is 2.7 g/cm3
100
One of these objects is the least dense.
What is C?
100
A physical change is this while a chemical change is not this.
What is reversible?
200
The state of matter has a definite volume but not a definite shape.
What is a liquid?
200
The difference between mass and weight
What is gravity
200
Carbon monoxide gas has a mass of 0.196 g and occupies a volume of 100 mL. Calculate the density and use the correct units. Hint: d = m ÷ v
What is 0.00196 g/mL
200
Styrofoam is a poor conductor of heat. This makes it a great choice as a coffee cup, compared to metal which is a good conductor of heat. This is an example of what property of matter?
What is thermal conduction?
200
Burning, rusting, changing color, and gas formation are all key indicators of what type of change?
What is a chemical change?
300

Justin found that 100nl of water and 20 ml of water boils at 100 degrees C. What can he conclude about his experiment?
The boiling point is the same temperature depending on the substance and doesn't depend on volume.
300
The equation to calculate the volume of a regular solid and units
What is L x W x H and cm3
