Materials with high conductivity are good conductors of electricity, while materials with low conductivity are poor conductors of electricity.<\/p>\n<p>The four materials in the question are copper, aluminium, steel, and silver. Copper is the best conductor of electricity, followed by silver, aluminium, and steel. Therefore, the correct order of decreasing conductivity is D. Silver, Copper, Aluminium, Steel.<\/p>\n<p>Here is a table showing the conductivity of the four materials:<\/p>\n<p>| Material | Conductivity (Siemens per meter) |<br \/>\n|&#8212;|&#8212;|<br \/>\n| Silver | 62.5 x 10^6 |<br \/>\n| Copper | 58.5 x 10^6 |<br \/>\n| Aluminium | 36.8 x 10^6 |<br \/>\n| Steel | 10^6 |<\/p>\n<p>As you can see, silver has the highest conductivity, followed by copper, aluminium, and steel.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[25],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Which of the following is arranged in order of decreasing conductivity?
