Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Dissolving Alumina in Cryolite reduces it's melting point to ____________ degree celsius.

• A. 1000
• B. 2000
• C. 3000
• D. 4000

Answer 1

The correct option is A 1000

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The melting point of alumina is around 2000 degree celsius which is too high. To solve this, the alumina is dissolved in a material called cryolite. The resulting mixture’s melting point is 1000 degree celsius.
