alleryAluminium's rank by abundance among all elements in the crust is
- First
- Third
- Second
- Fourth
Show answer and solution
Correct answer: B. Third
Only oxygen and silicon are more abundant than aluminium in the crust, so it ranks third.

Worked practice questions
Borosilicate glass is valued mainly for its
- High electrical conductivity
- Deep blue natural colour
- Resistance to thermal expansion
- Ability to dissolve in water
Show answer and solution
Correct answer: C. Resistance to thermal expansion
Adding boron gives glass much greater resistance to thermal expansion than ordinary glass.
