MULTIPLE CHOICE QUESTION
30 sec • 1 pt
If the mass of an object increases while its volume remains the same, its density will
increase
decrease
remain the same
Answer explanation
We are adding more molecules into the same amount of space. There will be less room for all of the molecules so they will be more compact.
More compact=higher density

MULTIPLE CHOICE QUESTION

If the mass of an object decreases while its volume remains the same, its density will
increase
decrease
remain the same
Answer explanation
If the mass is decreasing, the amount of molecules inside the object is lowered. That means there is more space between the molecules that are left behind, they are less compacted.
Less compact = lower density.

If the volume of an object increases while its mass remains the same, its density will
increase
decrease
remain the same
Answer explanation
More volume mean more space for the molecules. Since the mass is constant, we are not adding more molecules into the object. there will be more space between the molecules and they will be less compacted.
Less compact = lower density.

If we decrease the volume of an object and keep the mass constant, the density will
increase
decrease
remain the same
Answer explanation
Decreasing the volume means there is less space for the molecules. They will be closer to together, more compacted.
More compact = higher density

If we increase the temperature of a substance, its density will
increase
decrease
remain the same
Answer explanation
Increasing the temperature will make the molecules move faster and spread away from each other. They will be less compacted.
Less compact = lower density

If we decrease the temperature of a substance, its density will
increase
decrease
reamin the same
Answer explanation
Increasing the temperature will make the molecules move slower and get closer together. There will be less space between the molecules, they will be more compacted.
More compact = higher density.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
If we increase the pressure on a substance, the density will
increase
decrease
remain the same
Answer explanation
Increasing the pressure means we are squeezing the substance, lowering its volume. The molecules will be forced closer together and be more compacted.
More compact = higher density
