Energy Transfer: With and without particles

Select the state of matter which conduction is possible in.

• Solids

• Liquids

• Gas

Select an example of a good thermal conductor.

• Plastic

• Paper

• Wood

• Metal

Select the correct description of conduction.

• Heat passes from particle to particle, from colder to warmer areas.

• Heat passes from particle to particle, from warmer to colder areas.

• Heat jumps between particles, from warmer to colder areas.

• Heat jumps between particles, from colder to warmer areas.

Select what happens to particles during conduction.

• The particles stay still when heated.

• The particles vibrate when heated.

• The particles stay move heated.

• The particles disappear when heated.

Select the correct explanation of why conduction can not happen in liquids or gases.

• The particles are close together in liquids and gases.

• The gaps between the particles in liquids and gases prevent conduction.

• The particles in solids vibrate when heated.

• There is too much energy in liquid and gas particles.

Select the correct term for when 'heat rises' in liquids and gases.

• Conduction

• Convection

• Combustion

• Radiation

Select the correct term for the picture.

• A conduction current.

• A convection circuit.

• A convection current.

• A convection cycle.

Select the the correct description for what happens to particles in liquids and gases when they are heated.

• The particles increase their kinetic energy and fall.

• The particles lose their kinetic energy and rise.

• The particles increase their kinetic energy and rise.

• The particles lose their kinetic energy and fall

Select what happens when a liquid or gas is heated.

• Mass increases, volume decreases, density stays the same.

• Mass decreases, volume increases, density stays the same.

• Mass stays the same, volume increases, density increases.

• Mass stays the same, volume increases, density decreases.

Select the correct explanation for why a hot air balloon rises.

• Air inside in the balloon is heated, particles rise, the balloon expands, air in the balloon becomes less dense than air around it.

• Air inside in the balloon is cooled, particles rise, the balloon expands, air in the balloon becomes less dense than air around it.

• Air inside in the balloon is heated, particles sink, the balloon expands, air in the balloon becomes less dense than air around it.

• Air inside in the balloon is heated, particles rise, the balloon expands, air in the balloon becomes more dense than air around it.
