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.

Explanation:

• Conduction occurs when thermal energy is transferred through particle - to - particle collisions.
• Radiation is the transfer of thermal energy via electromagnetic waves.
• The gravitational force weakens as the distance between objects increases (inverse - square law \(F = \frac{Gm_1m_2}{r^{2}}\)).
• Friction depends on the mass (heavier objects have more normal force in many cases), surface roughness, and surface area.
• Convection is the transfer of thermal energy by the movement of a heated gas or liquid (bulk movement of fluid).

Answer:

Conduction, Radiation, Gravitational force, Friction, Convection
