Worked practice questions

Density is defined as the mass of a substance per unit:

  1. Volume
  2. Second
  3. Newton
  4. Degree
Show answer and solution

Correct answer: A. Volume

1. Density compares how much matter fits in a given space. 2. Density is the mass per unit volume of a substance or object. 3. Two objects of equal mass differ in density if their volumes differ. 4. It is crucial in determining whether an object sinks or floats in a fluid. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 11 'Fluid Statics', sections 11.1-11.9_

The SI unit for pressure is the:

  1. Watt
  2. Pascal
  3. Newton
  4. Joule
Show answer and solution

Correct answer: B. Pascal

1. Each physical quantity has its own SI unit. 2. The SI unit for pressure is the pascal. 3. Many other units for pressure are also in common use. 4. The newton, joule and watt measure force, energy and power instead. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 11 'Fluid Statics', sections 11.1-11.9_

Density is described as crucial for determining whether an object in a fluid will:

  1. Sink or float
  2. Heat or cool
  3. Glow or fade
  4. Melt or freeze
Show answer and solution

Correct answer: A. Sink or float

1. Density decides how an object sits in a fluid. 2. Density is the mass per unit volume of a substance or object. 3. It is crucial in determining whether an object sinks or floats in a fluid. 4. The comparison is between the object's density and the fluid's. _Source: OpenStax College Physics for AP Courses 2e (CC BY 4.0), Ch 11 'Fluid Statics', sections 11.1-11.9_
