Which of the following terms describes a texture containing bubble-shaped cavities formed during a physical or chemical change?

• A. Amorphous
• B. Vesicular
• C. Crystalline
• D. Granular

Answer: (B)

Verified step by step guidance

1. Understand the question is asking for a term that describes a texture characterized by bubble-shaped cavities formed during a physical or chemical change.
2. Recall that 'amorphous' refers to a solid lacking a defined crystalline structure, so it does not specifically describe bubble-like cavities.
3. Recognize that 'crystalline' describes a solid with an ordered, repeating atomic structure, which also does not imply bubble-shaped cavities.
4. Know that 'granular' refers to a texture made up of small grains or particles, not cavities or bubbles.
5. Identify that 'vesicular' is the term used to describe a texture containing small cavities or bubbles, often formed by trapped gas during solidification or chemical reactions.
