Chemistry Question on States of matter
A solid with high electrical and thermal conductivity is:
A
Si
B
Li
C
Nacl
D
Ice
Answer
Li
Explanation
Solution
In lithium crystal, free electronsare present, hence, Li has high thermal and electrical conductivity.
- As it is an alkali metal, it has an electron in its outermost orbital.
- Due to the free electrons, it has extremely high electrical and thermal conductivity.
A solid with high electrical and thermal conductivity is Lithium.
