Hard baked goods become soft in the microwave because the microwave heats up the moisture within the baked goods, causing it to evaporate and create steam. This steam then softens the texture of the baked goods, making them more moist and tender. The heat from the microwave also helps to break down the starches and proteins in the baked goods, further contributing to their softening. **

Rubber is vulcanized by adding sulfur to the rubber compound and then heating it. The sulfur forms cross-links between the long chains of rubber molecules, making the material more durable and elastic. This process changes the physical properties of the rubber, making it less sticky and more resistant to heat, wear, and aging. Vulcanization is a crucial step in the production of various rubber products, such as tires, hoses, and seals. **
