Chapter 1, "Matter in Our Surroundings,"
Based on Class 9 Science Chapter 1, "Matter in Our Surroundings," here are the statements extracted line by line: Matter and Its Physical Nature * Matter is made up of particles. * The particles of matter are very small; they are small beyond our imagination. Characteristics of Particles of Matter * Particles of matter have space between them. * When we make tea, coffee, or lemonade, particles of one type of matter get into spaces between particles of the other. * This shows that there is enough space between particles of matter. * Particles of matter are continuously moving; they possess what we call kinetic energy. * As the temperature rises, particles move faster. * Particles of matter attract each other. States of Matter * Matter around us exists in three different states: Solid, Liquid, and Gas. * Solid particles are closely packed, while liquid particles are less closely packed, and gas particles are far apart. ...
