When scientists are doing research to determine how the environment affects a life form, it often takes many years to reach a co

nclusion. Why do you think that is the case?
a.
Many environmental factors must be considered (water, light, and temperature were just three that were investigated in this simulation).
b.
Many tests must be performed because variables need to be tested one at a time (first test for water effects, then test for light effects, etc.).
c.
Some effects take a long time to become noticed, so the experiments often have to take place over long periods of time.
d.
All of the above.

Explain how the boiling of water and the cooling of water vapor is a reversible reaction.​ With hydrogen bonds between water mol
My name is Ann [436]

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.
