Matter in Our Surroundings
Matter
• All things which we see around us and use in our everyday life together constitute matter.
• Anything which occupies space and has mass is called matter.
• Matter is made up of particles.
States of Matter
• Matter can be classified as solid, liquid and gas on the basis of interparticle forces and the
arrangement of particles.
• These three forms of matter are interconvertible by increasing or decreasing pressure and
temperature. For example, ice can be converted from solid to a liquid by increasing the
temperature.
