As the more energetic form of water -- water vapor -- is formed, the liquid water chills. Thus conservation of energy is preserved. Mass of course remains the same.

What are the energy changes involved when water evaporates?
when water evpourates it turns into vapour and is present in the atmosphere in the form moisture so mass is conserved
What is conserved in physical changes?
Mass and energy
When water evaporates does its mass decrease?
The mass remain unchanged.
How are energy and mass conserved by living systems?
Not quite sure what you mean; let's just say that living systems don't require any extraordinary efforts to conserve energy and mass, because that's what they do naturally, i.e., "be conserved". There is no known way to violate conservation of energy or mass.
How is energy conserved with nuclear fission?
Energy is always conserved. You can neither create nor destroy energy. The same goes for mass. They can only be moved from one frame of reference to another. Fission has nothing to do with it. Ditto for fusion.One area of "confusion" for many people is Einstein's mass-energy equivalence equation e = mc2. Some people think it means that mass can be converted to energy and vice versa. Nope. Not even close. Mass is energy, and energy is mass. Think about that.
How do you explain how mass and energy are conserved when water evaporates?
mass of liqid water before evaporation=mass of liquid water after evaporates + mass of gaseous water.
What are the energy changes involved when water evaporates?
when water evpourates it turns into vapour and is present in the atmosphere in the form moisture so mass is conserved
Which is not conserved mass acceleration energy momentum?
Acceleration is not conserved. Energy can not be created nor destroyed. Mass and momentum are both conserved through a set time.
How can energy be conserved from a nuclear weapon?
A tiny bit of the mass of each fissioned (or fused) atom is converted to energy. Energy is not conserver... Mass-Energy is conserved.
What is conserved when one balances a chemical equation?
Mass (Matter) and Energy is conserved during a Chemical equation
When did albert Einstein invent e equals mc2?
In the beginning of the 20th century. He proposed mass-energy equivalence in 1905, and set out to mathematically express this. E = mc2 shows that energy can be converted into mass, and mass into energy. Thus, we no longer say that mass is conserved, or energy is conserved. But rather, we say that mass-energy is conserved.
Is energy conserved in a nuclear reaction?
Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.
Is energy is conserved when an atom emits a photon of light?
Energy is ALWAYS conserved. The appropriate sum of mass and energy is always conserved. If an atom emits a photon, the atom has less energy/mass, and the universe minus that atom has more energy/mass. It's like carrying some energy from here to there.
In a nuclear reaction WHAT does not have to be conserved?
While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.
What is conserved in physical changes?
Mass and energy
What is the exception for conservation of energy?
Energy isn't conserved in a process where there's a trade between mass and energy according to E = m c2 . When both mass and energy are tallied, the total is conserved.
Why law of conservation of mass should better be called as law of conservation of mass and energy?
Because energy can be converted into mass and vice versa. Thus, while the mass of a system is not conserved in a particular process, the mass and energy of a closed system is always conserved.
