• what is the matter it is anything that occupy space [volume] and has mass
• it is anything that occupy space [volume] and has mass- matter
• mass is how much an object contain
• is how much an object contain- matter
• volume is the amount of space occupied by the object
• is the amount of space occupied by the object - volume
• unit of mass

• matter -is made of tiny particles

  -these particles are called atoms or molecules
• -is made of tiny particles -these particles are called atoms or molecules - matter is made of
• these idea are proposed by the greek philosophers,democritus
