Question

3. Pedro threw a penny into a fountain and it sank to the bottom. Which of the following would explain

why the penny sinks?
A. The mass of the penny is more than the mass of the water.
B. The density of the penny is more than the density of the water.
C. The volume of the penny is more than the volume of the water.
D. The temperature of the penny is more than the temperature of the water.

Answer 1

its B because we're not talking about mass even tho most people would have chosen A cuz it says mass and u they would think its apart of density but if ur testing to see density ur figuring out which object will sink and which one will float so da reason why da penny snuck it cuz da density is greater den da water and copper has a better chance of sinking den floating so dats why its B I hope dis helps :3

Answer 2

B.

Step-by-step explanation:

A is not correct as there is much more water then penny meaning the water has more mass. The same can be said about C as the water also has more volume. Answer D is incorrect as the temperature of the penny is irrelevant to its ability to sink. That leaves us with option B, which is true as the penny is composed of metal allowing it to sink in the water due to having more density.
