Why are the heating elements of electric appliances like heaters made of alloys (e.g., Nichrome) rather than pure metals?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1Alloys conduct heat much faster due to lower density.
- 2Alloys possess a significantly lower melting point.
- 3Alloys do not readily oxidize (burn) at high temperatures.✓
- 4Alloys have lower electrical resistivity than pure metals.
Correct answer
Alloys do not readily oxidize (burn) at high temperatures.
