density ductility specific heat boiling point
I am hesitating between 4 options to answer the following question, which option should I choose?
Question: An engineer was given an assignment to build a model rocket. The main requirement was that it had to build it out of a metal that could release the energy that built up when reentering the atmosphere of Earth. What property should the engineer concentrate on the most when designing the rocket?
Possibilities:
- density
- ductility
- specific heat
- boiling point

specific heat
