If an object has a mass of 144 g and 120 mL, which of the following liquids would the object float in? (Check all answers that apply)

• Liquid A (Density of liquid = 1.1 g/mL)

• Liquid B (Density of liquid = 1.3 g/mL)

• Liquid C (Density of liquid = 1.5 g/mL)

Which of the following is a true statement? (There is only one correct choice)

• An object with a density of 1.2 g/mL will float in water.

• An object with a density of .8 g/mL will float in water.

• An object with a density of 1.0 g/mL will sink in water.

A student observes that ice floats in water. The student can conclude

• The density of ice is less than the density of water

• The density of ice is greater than the density of water

• The density of ice is equal to the density of water

Which of the following objects will sink in water? (Check all that apply)

• Object A (Density = 1.5 g/mL)

• Object B (Density = .5 g/mL)

• Object C (Density = 1.0 g/mL)

• Object D (Density = 2.0 g/mL)

Which of the following statements is true if an object is suspended in a liquid. (One correct answer)

• The object's density is greater than the density of the liquid.

• The object's density is less than the density of the liquid.

• The object's density is equal to the density of the liquid.
