Which type of heat transfer occurs through direct contact between materials?

• Conduction
• Evaporation
• Radiation
• Convection

What type of heat transfer is responsible for the warmth we feel from the sun?

• Radiation
• Convection
• Conduction
• Insulation

Which type of heat transfer occurs in fluids due to the movement of currents?

• Convection
• Conduction
• Radiation
• Insulation

What happens to the motion of particles as temperature increases?

• The motion of particles increases as temperature rises.
• The motion of particles stops completely at high temperatures.
• The motion of particles remains constant regardless of temperature changes.
• The motion of particles decreases as temperature rises.

How does convection differ from conduction?

• Convection is a process that requires no movement, while conduction relies on movement.
• Convection involves fluid movement for heat transfer, while conduction involves direct contact.
• Convection occurs only in solids, while conduction occurs in liquids and gases.
• Convection transfers heat through radiation, while conduction transfers heat through fluid movement.

What is a practical example of radiation?

• The taste of salt.
• The heat from a fire.

• The sound of thunder.
• The color of the sky.

Why do metals feel colder than wood at the same temperature?

• Wood retains heat better than metals due to its density.
• Metals are colder because they are made of a different element than wood.
• Metals are colder because they are heavier than wood.
• Metals feel colder than wood because they conduct heat away from the body more efficiently.

What is the role of particle motion in heat transfer?

• Particle motion has no effect on heat transfer.
• Heat transfer occurs only through radiation, not particle motion.
• Particle motion is irrelevant in conduction and convection.
• Particle motion facilitates the transfer of energy in conduction, convection, and radiation.
