Pressure: JAMB Physics Past Questions and Answers

What the JAMB syllabus covers in Pressure

Our summary: Atmospheric pressure and barometers, and pressure in liquids including Pascal's principle.

• Atmospheric pressure ((i) definition of atmospheric pressure; (ii) units of pressure (S.I) units (Pa); (iii) measurement of pressure; (iv) simple mercury barometer, aneroid barometer and manometer; (v) variation of pressure with height; (vi) the use of barometer as an altimeter.)
• Pressure in liquids ((i) the relationship between pressure, depth and density ($P = \rho g h$); (ii) transmission of pressure in liquids (Pascal's Principle); (iii) application.)

Objectives

• recognize the S.I units of pressure (Pa);
• identify pressure measuring instruments;
• relate the variation of pressure to height;
• use a barometer as an altimeter;
• determine the relationship between pressure, depth and density;
• apply the principle of transmission of pressure in liquids to solve problems;
• determine and apply the principle of pressure in liquid.
