CHAPTER 07 - PROPERTIES OF MATTER | 9TH PHYSICS NOTES

Qasim Tariq 11-01-2020Notes


After studying this unit, the students will be able to:

  • state kinetic molecular model of matter (solid, liquid and gas forms).
  • describe briefly the fourth state of matter i.e. Plasma.
  • define the term density.
  • compare the densities of a few solids, liquids and gases.
  • define the term pressure (as a force acting normally on unit area).
  • explain how pressure varies with force and area in the context of everyday examples.
  • explain that the atmosphere exerts a pressure.
  • describe how the height of a liquid column may be used to measure the atmospheric pressure.
  • describe that atmospheric pressure decreases with the increase in height above the Earth's surface.
  • explain that changes in atmospheric pressure in a region may indicate a change in the weather.
  • state Pascal's law.
  • apply and demonstrate the use with examples of Pascal's law.
  • state relation for pressure beneath a liquid surface to depth and to density i.e., (P=pgh) and solve problems using this equation.
  • state Archimedes principle.
  • determine the density of an object using Archimedes principle.
  • state the upthrust exerted by a liquid on a body.
  • state principle of floatation.
  • explain that a force may produce a change in size and shape of a body.
  • define the terms stress, strain and Young's modulus.
  • state Hooke's law and explain elastic limit.

Aim and Purposes:

Education is very expensive nowadays. Our only purpose is to educate everyone for free. We want to bring an educational revolution. Our aim is that nobody should be left behind, everyone should get knowledge and quench his thirst for knowledge. For this noble cause, we have hired a lot of experienced teachers and technical experts, who are serving you without any cost. If you want to be a part of this noble cause, you can contact us at join@educatedzone.com

Report a mistake:

EducatedZone has been working for the help of students since 2017. With the passage of time, many senior students and teachers have joined our team to become the part of this noble cause. They provide us notes and helping material to share with public. As different persons are notes provider so there may be a chance of mistake in some notes. Although it happens rarely, but if you find some mistake in the helping material, you can report it at teameducatedzone@gmail.com
