MCQ States of Matter Chapter 1 Class 9 Science MCQ’s For All Chapters – Science Class 9th 1. Liquids are called fluids because: Particles of a liquid have no force of attraction between them.Particles of a liquid have spaces between them.Liquids do not fill the whole container in which they are placed.Liquids can flow.Your comments:Question 1 of 202. When we put some crystals of potassium permanganate in a beaker containing water, we observe that after sometime, the whole water turns pink. This is due to:Brownian motionMeltingSublimationDiffusionYour comments:Question 2 of 203. A stream of water cannot be cut by fingers. Demonstrate that. Particles of matter attract each other.Particles of matter have spaces between them.Particles of matter are continuously moving.None of the above.Your comments:Question 3 of 204. Which of the following state of matter takes the shape of container in which it is filled?SolidLiquidGasBoth liquid and gas.Your comments:Question 4 of 205. Look at the figure given below. The increasing dilution of potassium permanganate solution with water fades the pink colour of the solution. This explains which property of matter?Matter is indivisible.Particles of matter are very very small.Particles of matter occupy space.Particles of matter are in continuous motion.Your comments:Question 5 of 206. Which of the following state has maximum intermolecular forces of attraction? WaterWater vapourIceSame in all states of matter.Your comments:Question 6 of 207. Sponge is a solid yet we are able to compress it. Why?A sponge is a porous substance in which water is trapped.A sponge is hollow solid in which air is trapped.A sponge is a delicate solid in which oxygen gas is trapped.A sponge is a solid that has minute holes in which air is trapped.Your comments:Question 7 of 208. Spreading of fragrance of a burning incense stick in a room shows that:Particles of matter have spaces between them.Particles of matter attract each other.Particles of matter are constantly moving.None of the above.Your comments:Question 8 of 209. Name the state of matter which has least compressibility.LiquidSolidGasNone of the aboveYour comments:Question 9 of 2010. Why does a gas exert pressure on walls of the container?Because particles of gas are static.Because particles of gas hit the walls of container.Because particles of gas react with each other.None of the above.Your comments:Question 10 of 2011. When we put a drop of ink in water taken in a glass, it spreads in the water making the water in glass entirely coloured. Which property of matter does it exhibit?Particles of matter have spaces between them.Matter consists of large number of particles.Particles of matter are very small in size.Particles of matter are continuously moving.Your comments:Question 11 of 2012. What kind of energy does particles of matter possess?Sound energySolar energyElectrical energyKinetic energyYour comments:Question 12 of 2013. Why is the rate of diffusion of liquids higher than that of solids?In the liquid state, particles are tightly packed.In the liquid state, particles move freely as compared to solids.In solid state, particles have least force of attraction between the particles.In solid state, particles cannot be compressed easily.Your comments:Question 13 of 2014. What happens when you add sugar to water?Volume of water doubles.Volume of water decreases.Volume of water remains the same.None of the above.Your comments:Question 14 of 2015. What happens when we make tea, coffee or lemonade?Particles of one type of matter don't get mixed up with particles of other type of matter.Particles of one type form a layer over another type of matter.Particles of one type of matter form a covering around the particles of other type of matter.Particles of one type of matter get into the spaces of the other type of matter.Your comments:Question 15 of 2016. ASSERTION-Sugar and Salt both are easily dissolved in water. REASON – Sugar and Salt are solid hence it is easily dissolved in water.a.) Both Assertion and Reason are correct, and reason is the correct explanation for assertion.b.) Both Assertion and Reason are correct, and Reason is not the correct explanation for Assertion.c.) Assertion is true but Reason is false.d.) Both Assertion and Reason are false.Question 16 of 2017. ASSERTION-When sugar pour in water, then taste of water became a sweet. Reason-sugar completely dissolved in water with giving its own character.a.) Both Assertion and Reason are correct, and reason is the correct explanation for assertion.b.) Both Assertion and Reason are correct, and Reason is not the correct explanation for Assertion.c.) Assertion is true but Reason is false.d.) Both Assertion and Reason are false.Question 17 of 2018. ASSERTION-ice is float on water. REASON-ice is solid in naturea.) Both Assertion and Reason are correct, and reason is the correct explanation for assertion.b.) Both Assertion and Reason are correct, and Reason is not the correct explanation for Assertion.c.) Assertion is true but Reason is false.d.) Both Assertion and Reason are false.Question 18 of 2019. ASSERTION-ice is float on water. REASON- Density of ice is lesser than water.a.) Both Assertion and Reason are correct, and reason is the correct explanation for assertion.b.) Both Assertion and Reason are correct, and Reason is not the correct explanation for Assertion.c.) Assertion is true but Reason is false.d.) Both Assertion and Reason are false.Question 19 of 2020. ASSERTION-SI unit of mass is kg. REASON- meaning of kg is kilogram.a.) Both Assertion and Reason are correct, and reason is the correct explanation for assertion.b.) Both Assertion and Reason are correct, and Reason is not the correct explanation for Assertion.c.) Assertion is true but Reason is false.d.) Both Assertion and Reason are false.Question 20 of 20 Loading...
