Question

What statements are true about insulators and conductors?

Select all that apply.
1 )An insulator is a substance that allows light to pass through it.


2 )A conductor is a substance that does not allow light to pass through it.

3. )A conductor is substance that allows thermal energy to pass through easily.

4 ) An insulator is a substance that does not allow thermal energy to pass through it.

Answer 1

Statements 3 and 4 are true

Step-by-step explanation:

A conductor and an insulator has nothing to do with passage of light. In fact, passage of light depends on transparency of an object.

Hence, statements 1 and 2 are false.

A substance that allows passage of heat (thermal energy) and electric current through it is called a conductor. An insulator does not allow passage of thermal energy or electric current through it.

Hence, statements 3 and 4 are true.
