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?
Yes, when water evaporates, its mass does not decrease. The water molecules simply change from a liquid state to a gaseous state, but the total mass of the water remains the same.
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 much mass will the gas have if 100 grams of water evaporate into a gas?
Matter might look different after a physical change, but the kind of matter itself does not change. Its particles have not changed. They are just packed together differently.
How do you explain how mass and energy are conserved when water evaporates?
When water evaporates, the water molecules gain energy from the surroundings to overcome intermolecular forces and escape into the air as vapor. While the water loses mass during evaporation, this mass is not lost but rather converted into the potential energy of the water vapor. Therefore, the total mass and energy of the system (water and surroundings) remains constant, demonstrating conservation of mass and energy.
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
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.
What is conserved in physical changes?
Mass and energy
What is conserved during a reaction?
Both mass and charge
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.
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.
Which is not conserved mass acceleration energy momentum?
Energy is not conserved in some situations, especially in processes involving non-conservative forces like friction or air resistance. The conservation of mass, acceleration, and momentum are fundamental principles in physics.
What is conserved when one balances a chemical equation?
When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.
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 mass must be lost to produce energy. true or false?
False. Both mass and energy are conserved.
When water evaporates does its mass decrease?
Yes, when water evaporates, its mass does not decrease. The water molecules simply change from a liquid state to a gaseous state, but the total mass of the water remains the same.
