GCSE Physics – Particle Model of Matter Quiz

What does the Kinetic Theory of Matter suggest about particles?

• Particles are only present in gases.

• All particles are stationary.

• Particles do not exist in solids.

• Particles are always in motion.

According to the Kinetic Theory, how does temperature affect particle motion?

• Temperature changes cause particles to disappear.

• The lower the temperature, the faster the particles move.

• Temperature has no effect on particle motion.

• The higher the temperature, the faster the particles move.

What state of matter are particles packed tightly in a regular pattern?

• Solid

• Plasma

• Liquid

• Gas

What is the process called when a solid turns into a liquid?

• Freezing

• Melting

• Sublimation

• Condensation

What is density?

• A measure of how much space an object occupies, volume per object

• A measure of how much mass is packed into a given volume, mass per unit volue

• A measure of how much air an object contains, mass of air per object

• A measure of the weight of an object, in newtons

What does the Law of Conservation of Mass state?

• Mass is only conserved in physical changes, not chemical reactions.

• Mass can be created and destroyed easily.

• Mass decreases over time in a closed system.

• Mass cannot be created or destroyed in a closed system.

What happens to the particles of a substance during melting?

• Particles gain kinetic energy and start to vibrate faster.

• Particles lose all their energy.

• Particles spread out into a loser structure.

• Particles gain potential energy and bonds are broken.

What is specific heat capacity?

• The amount of thermal energy needed to change the state of 1 kg of a substance.

• The amount of thermal energy needed to raise the temperature of 1 kg of a substance by 1°C.

• The amount of thermal energy a substance can hold at one time.

• The temperature increase when thermal energy is applied to a substance.

What does absolute zero refer to?

• The highest possible temperature measured in Kelvin.

• The point at which a substance has maximum kinetic energy.

• The average temperature of space.

• The temperature at which all molecular motion stops.

What is the Ideal Gas Law represented by?

• PV = nRT

• F = ma

• V = IR

• E = mc^2
