Question

after radiation

1. why is radiation able to transfer heat even through empty space, while conduction and convection require matter?

1. predict which surface would heat up faster in sunlight: a dark, matt surface or a shiny, light surface. explain why.

1. give a real - world example where radiation is the main method of heat transfer. describe how radiation works in your example.

Explanation:

Answer:

1. Radiation transfers heat via electromagnetic waves, which do not need a medium, while conduction and convection rely on particle interactions that require matter.
2. A dark, matt surface. Dark, matt surfaces absorb more infrared radiation from sunlight than shiny, light surfaces.
3. Example: Heat from the Sun reaching Earth. The Sun emits infrared electromagnetic waves that travel through the vacuum of space to warm the Earth's surface, with no matter needed for transfer.
