Question

The process by which heat is transmitted through vaccum is

• A. Conduction
• B. Convection
• C. Radiation
• D. Transmission

Answer 1

Answer:

C. Radiation

• The process by which heat is transmitted through a vacuum is radiation.

• Radiation transfers energy through electromagnetic waves, meaning it does not require a material medium like a solid, liquid, or gas to travel.

• In contrast, conduction requires direct physical contact between particles, and convection relies on the movement of fluids, making them both impossible in a vacuum.
