- Q1The following are characteristics of the particulate nature of matter EXCEPTAll matter is made up of tiny particles.The particles are in constant motion.There are empty spaces in between the particles.There are no forces that act between the particles.30sS8MT-IIIa-b-8
- Q2Which of the following items is INCORRECT?all matter have definite volume.All matter have massAll matter occupy spaceall matter are made up of atoms.30sS8MT-IIIa-b-8
- Q3When solid turns into liquid, the following may take place EXCEPT ___________The particles break away from their positionsThe particles move more slowly.The particles vibrate fasterThe particles gain kinetic energy30sS8MT-IIIc-d-9
- Q4What happens when water is heated?The molecules of water lose energy.Their attraction can overcome their motion.The molecules of water gain more kinetic energy and they move faster.The molecules of water gain kinetic energy but vibrate in place.30sS8MT-IIIc-d-9
- Q5Why are solids almost incompressible?The particles are very heavyThe particles vibrate and rotateThe particles are packed close togetherThe particles are very larger30sS8MT-IIIa-b-8
- Q6All of the following are properties of liquid EXCEPTLiquids can flow out of a container and can be poured into another.The attraction between particles is stronger than those in solids.The particles are closer to one another, nudging one another as they move.The attraction between particles is weaker than those in solids.30sS8MT-IIIa-b-8
- Q7Which of the following is arranged according to decreasing movement of particles?Gas – solid – liquidliquid – solid – gassolid – liquid – gasGas – liquid – solid30sS8MT-IIIa-b-8
- Q8Drops of water appeared outside a glass pitcher containing cold fruit juice. What process has taken place?Condensationmeltingfreezingevaporation30sS8MT-IIIc-d-9
- Q9Anything that occupies space and has mass.temperatureMatterenergyvolume30sS8MT-IIIa-b-8
- Q10A process in which a solid changed to liquid is called ______________MeltingBoilingSublimationFreezing30sS8MT-IIIc-d-9
- Q11When substance freezes, its particles _____________Stop movingMove farther from each othermove in very disorderly mannermove closer to each other30sS8MT-IIIc-d-9
- Q12Which of the following describes condensation?Ground-level fog that we see on some cold days.Your eyeglasses fogging up when you go from an air conditioned room.d. All of theseThe water that collects on the outside of your glass.30sS8MT-IIIc-d-9
- Q13If you keep the water boiling for more than 10 minutes, what do you think will happen to the amount of water in the beaker?The volume of water remains the same because the temperature will then subside.The volume of the water will increase because condensation of water takes place.c. None of theseThe volume of water will decrease because there will be rapid evaporation of water.30sS8MT-IIIc-d-9
- Q14What happens when a sample of water turns to ice?energy is absorbed by the moleculesNew molecules are formedthe arrangement of molecules changed.The mass of sample is increased30sS8MT-IIIc-d-9
- Q15It is the smallest particle of an element that has all the properties of an element.AngstromNanoAtomMolecule30sS8MT-IIIe-f-10
