Final answer:
The density of the gel pen is 4g/cm³.
Step-by-step explanation:
Density is a measure of how much mass is contained in a given volume. To calculate density, you divide the mass of an object or substance by its volume. In the case of the gel pen, the mass is 8g and the volume is 2cm³. So the density would be:
Density = Mass / Volume
Density = 8g / 2cm³
Density = 4g/cm³
Jill's gel pen has a mass of 8 grams and a volume of 2 cubic centimeters. To find the density, which represents the mass per unit volume, you use the formula:
Density
=

Density is a fundamental property that helps describe the compactness of matter. In Jill's gel pen, the mass is evenly distributed within the volume it occupies. A high density indicates that a significant amount of mass is packed into a relatively small space. Understanding density is crucial in various fields, including materials science and engineering, as it provides insights into the physical characteristics and composition of objects.
