- Q3What happens to the movement of particles in a liquid compared to a solid?Particles repel each otherParticles vibrate in fixed positionsParticles move freely and randomlyParticles slide past each other30s
- Q4What is the term used to describe the change from a solid to a gas without passing through the liquid state?MeltingEvaporationSublimationCondensation30s
- Q5Which of the following best describes the movement of particles in a plasma?Particles repel each otherParticles move freely and carry an electric chargeParticles vibrate in fixed positionsParticles slide past each other30s

- Q7What is the process called when a gas changes into a liquid?CondensationMeltingSublimationEvaporation30s
- Q8What is the process called when a liquid changes into a solid?SublimationEvaporationFreezingCondensation30s
- Q9What is a pure substance?A substance that can only be found in the laboratory.A mixture of different elements.A substance with a fixed composition and distinct properties.A substance that can change its composition easily.30s
- Q10What is the difference between an element and a compound?An element is a pure substance, while a compound is a mixture.An element is composed of only one type of atom, while a compound is composed of two or more different types of atoms bonded together chemically.An element is made up of molecules, while a compound is made up of ions.An element is always a solid, while a compound can exist in any state of matter.30s
- Q11What is the difference between a heterogeneous mixture and a homogeneous mixture?A heterogeneous mixture has visibly different substances or phases, while a homogeneous mixture appears uniform throughout.A heterogeneous mixture can be separated by physical means, while a homogeneous mixture requires chemical reactions for separation.A heterogeneous mixture consists of elements, while a homogeneous mixture consists of compounds.A heterogeneous mixture has a fixed composition, while a homogeneous mixture can vary in composition.30s
- Q12What is the difference between a physical change and a chemical change?A physical change does not alter the composition or identity of a substance, while a chemical change results in the formation of new substances with different properties.A physical change occurs when energy is absorbed, while a chemical change occurs when energy is released.A physical change involves the conversion of a substance from a solid to a liquid, while a chemical change involves the conversion from a liquid to a gas.A physical change can be reversed, while a chemical change is irreversible.30s
- Q13What is the difference between a pure substance and a mixture?A pure substance is formed through a chemical reaction, while a mixture occurs through a physical blending of substances.A pure substance has a variable composition, while a mixture has a fixed composition.A pure substance is composed of only one type of substance, while a mixture is composed of two or more different substances.A pure substance is always a solid, while a mixture can be a solid, liquid, or gas.30s
- Q14Which of the following best describes a pure substance?A substance that can change its composition easily.A substance that can only be found in labs.A substance that is a mixture of different elements.A substance that is made up of only one type of element or compound.30s
- Q15Which of the following is an example of a compound?HeliumGoldWaterOxygen30s
