Question

1. match the sentences with the terms.

thermal energy is transferred when particles of substances collide.
electromagnetic waves transfer thermal energy from one object to another.
this weakens the farther that objects are apart.
this increases the heavier an object is, and the rougher and larger the surface is between it and another object.
thermal energy is transferred by the movement of a heated gas or liquid.
choices
friction
convection
gravitational force
radiation
conduction

Explanation:

• Conduction: Thermal energy transfer via particle collision.
• Radiation: Thermal energy transfer by electromagnetic waves.
• Gravitational force: Weakens with increased object separation.
• Friction: Increases with object weight, surface roughness, and size.
• Convection: Thermal energy transfer through heated gas/liquid movement.

Answer:

1. conduction
2. radiation
3. gravitational force
4. friction
5. convection
