All females in the territory of specific male mate with the male give birth to their pups and after staying for few months move back into the water.
hence, option C is correct
The answer is B. Water/H2O
It can last from 1 to 4 hours
Answer:
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
Explanation:
Water molecules are connected through the hydrogen bonding. When water is boiled the kinetic energy of water molecules increased and point is reached when kinetic energy is so high and water molecules overcome the external pressure and escape from the surface. Thus water molecules convert into vapors.
In case of cooling process extra energy is released. Vapors becomes cooled and kinetic energy decreased vapors are changed into liquid state.
When water is boiled water molecules changed into vapors when these vapors condensed water changed into liquid.
So it is reversible reaction.
