what physical properties can you use to differentiate between between silver spoon and a stainless steel spoon
Answers
The following physical properties can be applied to differentiate between a silver spoon and a stainless spoon.
1. Production of sound: When tapped with a metal coin,
- silver spoon gives a high-pitched bell tone.
- stainless spoon produces a dull tone.
2. Oxidization: When wiped the surface using a clean white cloth,
- silver spoon leaves black marks/residue (silver reacts with oxygen forming a blackish silver oxide residue). Silver becomes dull when exposed to air.
- stainless spoon does not produce these marks as it doesn't react with oxygen.
3. Thermal conductivity: When an ice cube is placed
- it melts faster in the silver spoon (silver has high thermal conductivity) making the spoon cool faster.
- it melts later in the stainless spoon and the spoon cools slowly.

Differentiate between silver spoon and a stainless steel spoon.
Explanation:
The stainless steel spoon is non-magnetic during manufacturing and the quality of magnetism is reduced. It is iron-based alloy and has high heat resistance. It is easy to clean and hygienic and stainless spoon can be recyclable.
A silver spoon appears white, lustrous, soft, very ductile and when it is exposed to air or oxygen the silver spoon gets dull while a stainless spoon doesn’t. Silver is softer than stainless steel.
