If I add a new material it can change the density. Match how changing each would change density.

• Sinks Better

• More Mass

• Floats Better

• Mass the density equal to the linquid

• Suspends Better

• More Volume

Which would be a better tool than a beaker for measuring volume?

• Triple Beam Balance

• Graduated Cylinder

• Ruler

Answer explanation

A graduated cylinder is specifically designed for measuring liquid volume accurately, making it a better tool than a beaker. It has marked measurements that allow for precise readings, unlike a beaker which is less accurate.

The instrument that could be used to determine the volume of an IRREGULAR shaped object like a ROCK is a _____. Use all lower case letters.

Answer explanation

To determine the volume of an irregularly shaped object like a rock, a graduated cylinder is used. By submerging the rock in water, the volume can be measured based on the water displacement.

Rohan is trying to find out the density of a block of wood he found in his backyard. What formula should he use to calculate the density?

• A. L x W X H

• B. Mass= Volume

• C. Mass/ Volume

A box has a mass of 50 grams and occupies a volume of 100 cm3. What is its density?

• A. 0.5 g/cm3

• B. 1 g/cm3

• C. 2 g/cm3

What would happen to an object placed in pure water if the following were true?

• Mass less than volume

• It would float.

• Mass=Volume

• It would sink.

• Mass greater than volume

• It would suspend.

A student accidentally labeled their density column with g/cm3 instead of g/mL. Which liquid would be water?

• liquid A

• liquid B

• liquid C

• liquid D

A submarine sinks by

• A. Decreasing its volume

• B. Increasing its mass

Answer explanation

If you add more stuff (mass) it can cause an object to sink. The shape and size (volume) of a submarine doesn't change.
