The mass of a large bouncy ball is 125 grams and has a volume of 145 cm squared What is its density?
Where would it end up in the density column? Explain.
The density of an object is calculated by dividing its mass by its volume. In this case, the mass of the bouncy ball is given as 125 grams, and the volume is given as 145 cm^3.
Density = Mass / Volume
Plugging in the given values:
Density = 125 grams / 145 cm^3
Dividing these values, we get:
Density = 0.862 grams/cm^3
Now, to determine where the ball would end up in the density column, we need to compare its density to the densities of different substances. If the density of the ball is less than the density of a particular substance, it will float on that substance. If the density of the ball is greater, it will sink in that substance.
For example, the density of water is approximately 1 gram/cm^3. Since the density of the ball (0.862 g/cm^3) is less than that of water, the ball would float if placed in water.
Similarly, if we consider the density of air (approximately 0.0012 grams/cm^3), the ball's density is much higher. Therefore, the ball would sink if placed in air.
To summarize, the large bouncy ball would float in water due to its density being less than that of water. In air, the ball would sink due to its density being higher than that of air.
