the size of the ice cube decreases because it get heat and it melts
steam is used to generate electricity. what happens to the steam after it has generated electricity?
yes becuase when the molecules in steam move faster than molecules in water and this creates more pressure
vapour/steam
Both steam and liquid water are made of the same substance (H2O). However, in the gaseous form (steam), the molecules are moving more quickly, and they are spread apart much farther. As such, the number of molecules per given volume (the mass per volume) is lower for steam. Mass per volume is the same thing as density.
Heat is atoms and molecules moving so they start moving.
the metal will become hot
When water molecules are heated and turned into steam they move faster causing more collisions. They also move farther apart.
Steam and Ice are made up of Water Molecules which are made up of two hydrogen atoms and one oxygen atom. Steam is water turned to gas by having its molecules excited by heat. Ice is water where the molecules have slowed down because of cold temperatures, forming a solid. Hope this helps.
If they speed up fast enough, they turn to steam (water vapor).
Steam is water molecules in vapor form
steam
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.

The faster a molecule moves, that hotter it becomes. If water becomes hot enough, it evaporates into steam.
