Which of the following correctly describes the law of conservation of energy quizlet
The law of conservation of energy states that energy neither creates nor destroys itself, but rather transforms from one form to another.
Which statement best describes the law of conservation of mass quizlet
According to the law of conservation of mass, neither chemical reactions nor physical transformations can create or destroy mass in an isolated system.
Which statement best describes the law of conservation of Mass
The mass of each product produced during a chemical reaction will be equal to the mass of each reactant.
Which statement best describes the energy conversion S in a moving car
There is only one transformation because the chemical energy of the fuel is converted to the mechanical energy of the vehicle in the engine of a car.
Which best describes the conversion of energy when fossil fuels are burned
These are all examples of energy conversion, which is the process by which one kind of energy transforms into another kind. When fossil fuels are burned, chemical energy transforms into thermal energy, which is then used to produce electrical energy.
What is the best term when describing energy of motion
Kinetic energy is the energy involved with an objects motion.
Which statement explains the law of conservation of matter
According to the Law of Conservation of Matter, although substances can change form during a physical change, their overall mass does not change.
Which statement best describes the law of conservation of mass ?( 1 point matter Cannot be created or destroyed in a chemical reaction
Mass and energy conservation The law of conservation of mass states that during a chemical reaction, neither new or old mass is created.
Which of the following best describes mechanical energy
The energy that an object possesses as a result of its motion or position is known as mechanical energy.
Which statement best explains the change that occurs when gas particles move more slowly
Which of the following statements most accurately describes the change that takes place when gas particles move more slowly?
Which of the following is best example of potential energy
Examples of Gravitational Potential Energy
- a heavier burden.
- water retentive to a dam.
- a car that is parked on a hilltop.
- before it is released, a yo-yo.
- River water at a waterfalls summit.
- A book before it topples over on a table.
- At the top of a slide, a child.
- Fruit just before it ripens.
What happens to energy when Sally kicks a soccer ball
When Sally kicks a soccer ball, kinetic energy is transferred from the leg to the ball, potential energy is converted to chemical energy in the muscles, and kinetic energy is transferred from the soccer ball to the muscles.
Which of the following is a way for the government to encourage efficient energy use quizlet
The government can promote energy conservation by improving public transportation, taxing electricity, oil, and natural gas, and providing rebates or tax credits for retrofitting a home or business to use less energy. It can also encourage or mandate that people use less energy in their daily lives.
Which of the following is the best example of an energy storage element in a solar energy system
Firewood, hydropower, and windmills/turbines are all powered by solar energy, making a hot water tank the best example of an energy storage component in a solar energy system.
Which of the following explains why some energy sources are renewable
Some energy sources are renewable because they can be replenished naturally at or close to the rate of consumption, which is explained by which of the following?
Which of the following energy sources is not derived directly or indirectly from solar energy
Geothermal energy, which is the heat energy produced and stored in the Earth, is the source of energy that is not directly or indirectly derived from solar energy.
Which of the following correctly describes the first part of the lifecycle of the sun
Which of the following best describes the first stage of the Suns lifecycle? The full sequence is 1. protostar, 2. main sequence, sub-giant, red giant, and asymptotic giant branch.
Which one of the choices below is not considered a fossil fuel quizlet
The right response is D because wood is not a fossil fuel but is used to create a biomass fuel. The main types of fossil fuels are oil, coal, and natural gas. They are all created from the remains of dead organic matter.
