Isopropyl alcohol has a density of 0.786 grams per cubic centimeter (g/cm3). An object has a mass of 13 grams (g) and a volume of 21 cubic centimeters (cm3). What will happen when the object is placed into isopropyl alcohol?
- The object will sink because it is more dense than isopropyl alcohol.
- The object will float because it is less dense than isopropyl alcohol.
- The object will float because it is more dense than isopropyl alcohol.
- The object will sink because it is less dense than isopropyl alcohol.

Answer

To determine whether the object will sink or float, we need to calculate its density and compare it to the density of isopropyl alcohol.

  1. Density of the object = Mass / Volume = 13 g / 21 cm3 = 0.619 g/cm3.
  2. The density of the object (0.619 g/cm3) is less than the density of isopropyl alcohol (0.786 g/cm3).
  3. Therefore, the object will float because it is less dense than isopropyl alcohol.
