Danielle, a student in a science class, has been asked to design an experiment examine the process of thermal equilibrium. She places two objects that have the same mass but different initial temperatures in contact with each other. She records the final temperature in a table after the heat has been transferred.

What substance has a mass of 9.5g and volume of 2.1cm^3
