Which task illustrates radiation being used to dry paint on a car?

• A. Sealing windows
• B. Drying paint
• C. Cleaning tires
• D. Lubricating engines

Answer: (B)

Radiation drying uses infrared energy to heat a wet coating from a distance, speeding up the evaporation of solvents without touching the surface. In car painting, exposing the fresh paint to radiant heat dries and cures the coating quickly, improving finish and throughput. The task that demonstrates radiation being used to dry paint is that drying process. The other options involve different functions—sealing windows to control heat transfer, cleaning tires to remove dirt, and lubricating engines to reduce friction—none of which describe drying a paint film with radiant heat.
