Classify the following accorsing to the nature of matter in them - whether it is made from one kind of matter or from more than one kind of matter; and whether it is in solid, liquid or gaseous state : an engraved idol, gold, milk, water, a plank, concrete, salt, soil, coal, smoke, sherbet, cooked khichadi, steam.
Answers
An engraved idol: Generally made up of one kind of matter and is solid in state
• Gold: It is made up of one kind of matter and is solid in state
• Milk: It is a colloidal mixture, hence made up of more than one kind of matter and is liquid in state
• Water: It is a solvent and hence is made up of one kind of matter and is liquid in state.
• A plank: Considering it’s a wooden plank, it must be made up of one kind of matter and is solid in state.
• Concrete: Concrete is a heterogeneous material and hence is made up of one kind of matter and is Solid in state.
• Salt: Assuming that the salt in reference is table salt, then it’s made up of one kind of matter only and is solid in state.
• Soil: Soil is a heterogeneous mixture and hence is made up of more than one kind of matter and is solid in state.
• Coal: It is made up of one kind of matter only and is solid in state
• Smoke: It is made up of more than one kind of matter and is gas in state.
• Sherbet: Depending upon the type of sherbet, it may be heterogeneous or homogeneous i.e. made up of one kind of matter only or more than one kind of matter.
• Cooked khichadi: It a heterogeneous mixture of rice and lentils and hence is made up of more than one kind of matter. It is generally semi solid in state.
• Steam: Steam is composed of one kind of matter only and is gaseous in state.
