The molecules of iron combine with molecules of oxygen to form molecules of iron oxide- or rust.
It starts rusting when water keeps on touching it.:)
new molecules starts to form
It starts to smell icky
Its molecules starts vibrating more than when they were solid. Their kinetic energy are greater.
when solute is dissolved in a solvent...the molecules of the solute starts diffusing between the particles of the solute.
An annual event starts with A and happens once a year.
Yes the oxygen acts as if it starts a chemical reaction.
When steel is heated, its molecules vibrate more vigorously than normal, thus gaining more kinetic energy. As steel starts melting at 1450 degrees Celsius, the particles break free of the bonds that hold them in the lattice.
Photosynthesis starts with 6 molecules of carbon dioxide and 6 molecules of water.
Nothing will happen because of the gravity
It starts to be on fire the it starts to smoke
It starts to freeze at 0oC , if heat is still withdrawn from the water: it is needed for the freezing of water molecules from the liquid phase to solid phase (ice) and during this temperature will remain 0oC.
