Science ACAP Review

Front

Matter is anything that has ___ and volume.

Back

mass

Answer explanation

Matter is defined as anything that has mass and volume. Mass refers to the amount of matter in an object, making 'mass' the correct choice, while 'weight' and 'shape' do not accurately describe this fundamental property.

Front

___ is the amount of matter in an object.

Back

Mass

Answer explanation

Mass is defined as the amount of matter in an object, while volume refers to the space an object occupies. Therefore, the correct answer is mass.

Front

___ is the amount of space an object takes up.

Back

volume

Answer explanation

Volume is the measure of the amount of space an object occupies, while area refers to the surface space. Therefore, the correct answer is volume.

Front

What is the unit of measurement for mass?

Back

grams

Answer explanation

The unit of measurement for mass is grams. Liters and cm3 are units for volume, not mass. Therefore, grams is the correct choice.

Front

What is the unit of measurement for volume?

Back

liters or cm3

Answer explanation

The unit of measurement for volume is liters or cubic centimeters (cm³). Grams measure mass, not volume, making liters and cm³ the correct choices for volume measurement.

Front

Mass is affected by changes in shape.

Back

False

Answer explanation

Mass is a measure of the amount of matter in an object and does not change with shape. Therefore, the statement that mass is affected by changes in shape is false.

Front

Are mass and weight the same?

Back

False

Answer explanation

Mass is a measure of the amount of matter in an object, while weight is the force exerted by gravity on that mass. Therefore, they are not the same, making the statement false.

Front

The density of a rock would need to be determined using the water displacement method.

Back

True

Answer explanation

True. The water displacement method is used to measure the volume of an irregularly shaped object, like a rock, which is necessary to calculate its density by dividing mass by volume.

Front

How is the density of a cube determined?

Back

Measure its mass and calculate its volume (lxwxh).

Answer explanation

True. To determine the density of a cube, you first measure its mass and then calculate its volume using the formula (length x width x height). Density is mass divided by volume.

Front

Which item is the most dense? Lead: 11.4 g/cm3, Aluminum: 3.7 g/cm3, Bone: 1.9 g/cm3, Gasoline: 0.68 g/cm3

Back

Lead: 11.4 g/cm3

Answer explanation

Lead has the highest density at 11.4 g/cm3, significantly more than aluminum (3.7 g/cm3), bone (1.9 g/cm3), and gasoline (0.68 g/cm3). Therefore, lead is the most dense item among the choices.
