Lesson: Density and PressurePhysics
In this lesson, we will learn how to calculate the density of materials and how to find the pressure at a given depth in a liquid of a given density.

A trash compactor can compress its contents to 0.350 times their original volume. Neglecting the mass of air expelled, how many times denser is the trash?
A cylindrical coffee cup holds 375 g of coffee when filled to a depth of 7.50 cm. Find the radius of the cup. Use a value of 1.00 g/cm3 for the density of coffee.
Find the mass of the air inhaled during a deep breath. Use a value of 2.00 L for the volume of the air and use a value of 1.29 kg/m3 for the density of air.
