A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements.
The statement that explains what an insulator does is that: An insulator slows heat transfer.
A substance could be;
- A thermal conductor
- A thermal insulator
A thermal conductor allows heat to pass through it easily. It facilitates heat transfer.
A thermal insulator does not allow heat to pass through it easily, it does not facilitate heat transfer.
Hence, an insulator slows heat transfer.
