What evidence supports a conservation law? Energy from sunlight becomes glucose during photosynthesis. Oxygen is combined with the carbon atoms left from the glucose molecule.
Which is the best example of the law of conservation of energy?
Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
How does this support the law of conservation of energy?
The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside.

Which statements best describe the law of conservation of energy?
Answer: The law of conservation of energy is the preserved form of energy. Option (1) is correct that is the total amount of energy in the universe remains constant. Because energy is conserved.

How do you prove the law of conservation of mass with an activity?
0:001:24Chemistry – Law of Conservation of Mass experiment – YouTubeYouTube
Which is an example of conservation of energy resources?
Turning off the light when you leave the room, unplugging appliances when they're not in use and walking instead of driving are all examples of energy conservation. The two main reasons people conserve energy are to gain more control over their energy bill and reduce the demand on the earth's natural resources.
What are 3 ways you can conserve energy?

What is conservation of energy give 2 example?
Law of Conservation of Energy Examples: In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy. In hydroelectric power plants, waterfalls on the turbines from a height. This, in turn, rotates the turbines and generates electricity.
What is conservation of energy give two example?
Daily life examples of Conservation of energy: 1) Human metabolism, the food we take gives us energy which we use to move, work, exercise, play. 2) When a moving car hits another car which is parked to make it move, energy of the moving car is transferred from the moving car to the parked car.
What are 3 examples of law of conservation of mass?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
How can you prove the law of conservation of mass?
The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.
What experiment can be done to prove the law of conservation of mass?

Which statement demonstrate the law of conservation of matter?
The Law of Conservation of Matter states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.
Which statements best describes the law of conservation of energy?
Answer: The law of conservation of energy is the preserved form of energy. Option (1) is correct that is the total amount of energy in the universe remains constant. Because energy is conserved.
Can you cite some other real life situations where you can apply the law of conservation of mechanical energy?
A baseball hits a window in a house, shattering the glass. The energy from the ball was transferred to the glass, making it shatter into pieces and fly in various directions. When a moving car hits a parked car and causes the parked car to move, mechanical energy is transferred from the moving car to the parked car.
Why do we need to conserve energy?
Saving energy reduces air and water pollution and conserves natural resources, which in turn creates a healthier living environment for people everywhere. At the same time, efficiency also saves money and creates jobs.
Which of the following is the best example of law of conservation of mass?
A sample of air increases in volume when heated at constant pressure but its mass remains unaltered.
How do you prove kinetic energy is conserved?
An elastic collision is one where kinetic energy is conserved. The masses that collide don't deform from the collision nor do they stick together. An example of this would be pool balls colliding. Inelastic collisions occur when masses collide and stick together and/or there is deformation of either or both masses.
What are two ways that energy can be conserved?
Energy conservation can be as simple as turning off lights or appliances when you do not need them. You can also use energy-intensive appliances less by performing household tasks manually, such as hang-drying your clothes instead of putting them in the dryer, or washing dishes by hand.

What was one of the experiments that was performed to support the idea of mass conservation?
Lavoisier believed that when a substance burns, oxygen from air combines with that substance to form a new substance. His experiments showed that new product weighed more than the original substance by a mass equal to the amount of oxygen that reacted with the substance.
