Mick has a very detailed model of the solar system where each planet is made out of granite rock. Since his little sister really liked the model, he spent two weeks in his dad's workshop building her a Styrofoam copy. When he picked up the models to take them back inside the house, which physical property would he immediately notice upon picking them up?

Mick has a very detailed model of the solar system where each planet is made out of granite rock. Since his little sister really liked the model, he spent two weeks in his dad's workshop building her a Styrofoam copy. When he picked up the models to take them back inside the house, which physical property would he immediately notice upon picking them up?

A.
density
B.
ductility
C.
conductivity
D.
color

Answer 1

A. density

Mick would immediately notice the difference in density between the granite rock model and the Styrofoam model when he picked them up. The granite model is much denser and heavier than the lightweight Styrofoam model.
