When a liquid-fuel rocket takes off, it can switch its gas jet from side to side, correcting any tendency to veer off course. But solid-fuel rockets have no separate combustion chamber ...

Students explore the attractions and motion of atoms and molecules as they experiment with and observe the heating and cooling of a solid, liquid, and gas.

The density of solid iron = 7.8 g/cm 3 The density of liquid iron = 6.9 g/cm 3 A substance evaporates when it changes from the liquid state to the gas state. Its particles move freely and are very ...
