The half life, this is how long it takes for half of the atoms to decay
Answer:
A. 2
Explanation:
A particle of water is made up of two hydrogen atoms and one oxygen atom. However, the question asked for how many types of atoms there are, so the answer is 2.
'The slower moving' type of water molecules have the greater tendency to condense to the liquid state from the gaseous state.
If the molecules speed up it means that energy has been added to the system. Eventually, therefore, the water would evaporate into steam (or water vapour) provided the energy was continued to be added to the system.
Vice versa if the molecules are slowed down then the water molecules in gas would condense and change their state from gas to liquid.
Condensation is the process where water vapour becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapour.
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapour that it cannot hold any more water.
