In which state of matter do particles have the highest kinetic energy?

Gas

Why do liquids generally have lower density compared to solids?

Liquids have weaker force of attraction between particles

What determines the ability of a gas to exert pressure on the walls of a container?

Why can we easily move our hand in air but not through a solid block of wood?

Wood particles have stronger force of attraction than air particles

Study Notes

  • Matter exists in three states: solid, liquid, and gas, with each state having different characteristics due to variations in the particles of matter.
  • The physical properties of matter have been classified based on physical properties, with chemical properties to be discussed in subsequent chapters.
  • Early Indian philosophers classified matter into five basic elements, while modern scientists have evolved classifications based on physical and chemical nature.
  • Matter is made up of particles, as shown in the magnified schematic pictures of the three states of matter, with particles exhibiting different motions in each state.
  • Density is the mass per unit volume of a substance, and examples are given to arrange in increasing order of density such as air, exhaust from chimneys, honey, water, chalk, cotton, and iron.

Test your knowledge on properties of matter with questions on what constitutes as matter, observations related to smell, properties of matter demonstrated by a diver, and characteristics of particles of matter.
