Consider the following facts.

1. Copper nanoparticles are more malleable and ductile than bulk copper.
2. A bulk material should have constant physical properties regardless of its size, but at the nanoscale this is often not the case.

Which of the statements given above is/are true?

Nanoparticles exhibit a number of special properties relative to bulk material. For example, the bending of bulk copper (wire, ribbon, etc.) occurs with movement of copper atoms/clusters at about the 50 nm scale. Copper nanoparticles smaller than 50 nm are considered super hard materials that do not exhibit the same malleability and ductility as bulk copper.
