MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Media Image

What type of heat transfer is shown in Diagram A?

radiation

convection

conduction

insulation

Answer explanation

Diagram A illustrates convection, which is the transfer of heat through the movement of fluids (liquids or gases). This process involves warmer areas rising and cooler areas sinking, creating a circulation pattern.

Media Image

What type of heat transfer is shown in Diagram B?

radiation

convection

conduction

insulation

Answer explanation

Conduction is the transfer of heat through direct contact between materials. In Diagram B, if heat is being transferred through solid objects touching each other, it illustrates conduction.

Media Image

What type of heat transfer is shown in Diagram C?

radiation

convection

conduction

insulation

Answer explanation

Diagram C illustrates heat transfer through radiation, which occurs when heat is emitted as electromagnetic waves. Unlike conduction and convection, radiation does not require a medium to transfer heat.

Heat makes particles of matter move

faster

slower

down

sideways

Answer explanation

Heat increases the energy of particles, causing them to move faster. Therefore, the correct answer is 'faster', as heat directly correlates with the speed of particle movement.

Media Image

The movement of water upward in the beaker is due to

particles of water expanding and contracting

air movement across the surface of the water

the shape of the beaker

mystical unknown forces

Answer explanation

The movement of water upward in the beaker is primarily due to particles of water expanding and contracting, which affects their density and causes them to rise. This is a physical property of liquids, not influenced by air movement or beaker shape.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Most metals are

good conductors.

poor conductors.

good insulators.

neither conductors nor insulators.

Answer explanation

Most metals are good conductors of electricity and heat due to their free-moving electrons. This property allows them to efficiently transfer energy, making 'good conductors' the correct choice.

7.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

When heated most substances

contract.

expand.

expand and contract.

do not change.

Answer explanation

When heated, most substances expand due to increased kinetic energy, causing their particles to move apart. Therefore, the correct answer is that they expand.
