The particles in a liquid are:Packed close together and can vibrateSpread far apart and move randomly in all directionsQuite close together and can move past each otherSpread far apart and cannot move at all2Which state of matter has no fixed shape and volume and can be compressed?SolutionGasSolidLiquid3During which change do particles lose energy to the surroundings?BoilingSublimingMeltingFreezing4Condensing is when a substance changes from:Solid to gasSolid to liquidLiquid to gasGas to liquid5Sublimation is when a substance changes from:Solid to gasLiquid to gasSolid to liquidGas to liquid6A substance has a melting point of -5°C and a boiling point of 66°C. What is its state at room temperature (20°C)?SolutionLiquidGasSolid

In which process do particles move closer together but remain in motion?A condensationB diffusionC evaporationD freezing

Which of the following statements does NOT apply to the particles in a liquid?They can move around one another (flow)They move randomly so as to fill the entire volume of their containerThe bonds between them are weaker than those between the particles in a solidThey are packed closely2What is meant by the internal energy of a system?The total kinetic and potential energy of the particles it containsThe total kinetic energy of the particles it containsThe energy which its particles release when they undergo nuclear reactionsThe total potential energy of the particles it contains3Under the right conditions, a substance can change directly from a solid to a gas.  What is this process called?EvaporationDepositionSublimationVaporisation4Which of the following processes can occur when the internal energy of a gas decreases?CondensationEvaporationFreezingSublimation5Which of the following does NOT apply to a physical change?It involves a change in the internal energy of a substanceNo new substances are formedMass is conserved (the mass before the change is equal to the mass after the change)The change is irreversible

What happens to ice as it melts?A.The average kinetic energy of the water molecules increases.B.The absorbed energy breaks apart intermolecular forces.C.The released energy increases the intermolecular forces.D.The average kinetic energy of the water molecules decreases.
