What process, involving heating rubber with sulfur, was developed to make natural rubber more durable and elastic?

Explanation

Vulcanization is a chemical process in which natural rubber is heated together with sulfur, creating cross-links between rubber molecules that make the resulting material far stronger, more elastic, and more resistant to temperature changes than untreated rubber. This process was developed by Charles Goodyear in the nineteenth century and made rubber practical for uses like vehicle tires. Untreated natural rubber, by comparison, tends to become brittle in cold weather and sticky in heat. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
