Question

Mark places four objects in a tank of water. He makes the following observations. · A beach ball floats. · A penny sinks. · A soda can floats. · A piece of chalk sinks. Which statement is correct based on Mark's observations? Question options:

a.The beach ball and the can of soda have a density greater than water.


b.The beach ball and the can of soda have a density equal to water.


c.The penny and the chalk have a density greater than water.


d.Small objects always sink in water.

Answer 1

the density of objects in ascending order is
beach ball and can of soda<water<penny and chalk.


so c is the option that perfectly matches

Answer 2

Based on Mark's observation, the option C.The penny and the chalk have a density greater than water is correct.

Explanation:

Density of water in the tank is approximately 1 g/cm3.

If an object has density more than 1 g/cm3, it will sink in water.

If an object has density less than 1 g/cm3, it will float.

Hope it helps. Thanks.
