Energy

The form of energy stored in the grass is chemical energy. This energy is stored in the bonds of the molecules within the grass through the process of photosynthesis.

Sunlight

The energy from water falling over a dam is primarily potential energy that is converted into kinetic energy as it flows through turbines to generate electricity.

The two most widely used forms of energy in Canada are hydroelectricity and natural gas. Hydroelectricity is generated from water flowing through turbines in hydroelectric dams, such as the Hoover Dam in British Columbia. Natural gas is used for heating homes, powering industrial processes, and generating electricity, for example, in Alberta's natural gas power plants.

The energy for photosynthesis comes from sunlight, which is captured by chlorophyll molecules in the chloroplasts of plants. This energy is used to convert carbon dioxide and water into glucose and oxygen.

TRUE

If the temperature of an object doubles, the total amount of its thermal radiation will increase by a factor of 16. This is because the rate of thermal radiation is proportional to the fourth power of temperature according to the Stefan-Boltzmann law.

Potential energy is the energy an object possesses due to its position or condition. It is stored energy that can be converted into kinetic energy when the object moves or changes state. Examples include gravitational potential energy and elastic potential energy.

The energy of atoms and molecules in an object due to their motion is called kinetic energy. This energy is a result of the random motion of particles within the object. The temperature of an object is a measure of the average kinetic energy of its constituent particles.

False. Kinetic energy is related to an object's motion or speed, not its height. Potential energy is related to an object's height, while kinetic energy is related to its motion.

The stored energy in beans comes from the sun, through photosynthesis where plants convert sunlight into chemical energy. The energy in coal comes from ancient plants and organic matter that were buried and fossilized millions of years ago.

When thermal horizontal movement is a factor, a slip expansion joint hanger is commonly used. These hangers allow for lateral movement due to temperature changes, preventing stresses on the piping system.

Potato chips have high energy levels because they are deep-fried in oil, which increases their calorie content. They also contain a high amount of fat and carbohydrates, which are sources of energy for the body when consumed.

That is called the "efficiency" of the device.

In a fan heater, electrical energy is converted into thermal energy through a heating element (such as a metal coil). The thermal energy is then transferred to the surrounding air through convection, where the fan blows the heated air out into the room, transferring thermal energy to the surroundings.

Sound energy is a form of energy that can be heard. It is produced by vibrations that travel through a medium, such as air or water, and can be perceived by the human ear. Sound energy is essential for communication and plays a significant role in our daily lives.

The cells that harness the sun's energy for electricity are called solar cells, or photovoltaic cells. These cells convert sunlight directly into electricity through the photovoltaic effect.

The energy produced is obviously light energy. The energy is provided by the bicycle's kinetic energy.

Ionic, covalent, and metallic bonds are the three primary types of chemical bonds. Ionic bonds involve the transfer of electrons between atoms, forming positively and negatively charged ions that are attracted to each other. Covalent bonds involve the sharing of electrons between atoms, creating a strong bond due to the sharing of electron pairs. Metallic bonds involve the delocalization of electrons in a sea of electrons that are shared among all atoms in a metal structure, resulting in high electrical conductivity and malleability.

The cost of electrical energy is computed per energy unit. The more energy you use, the more you will be charged. The unit normally used is the kWh (kilowatt-hour), which is equal to 3,600,000 watt-seconds or joules.The cost per kWh is, at least roughly, determined by supply and demand.

When a book hits the floor, the potential energy of the book is transformed into kinetic energy as it falls. Upon impact, some of the kinetic energy is converted into sound and heat energy, resulting in the book coming to a stop.

Blue and violet light have the shortest wavelengths in the visible light spectrum.
