Which of the following two properties of metals are exploited to prepare very thin sheets of silver to decorate sweets?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Malleability and Lustre.
To prepare the thin silver sheets (called varak or vark) used for decorating Indian sweets, two key properties of metals are exploited: malleability and lustre. Malleability is the ability of a metal to be hammered or rolled into thin sheets without breaking. Silver, being highly malleable, can be made into ultra-thin foils. Lustre refers to the shiny appearance of metals, which makes the sweets look attractive and luxurious. These silver sheets are edible and safe when properly prepared. The process highlights silver’s physical properties, making it ideal for decorative culinary uses.
Other options :
-
Ductility and Lustre: Ductility relates to drawing metal into wires, not sheets.
-
Lustre and Sonorous: Sonorous means producing sound—irrelevant here.
-
Malleability and Sonorous: Sonorous doesn’t apply to food decoration.
