How much of the chemical energy in the fuel of a petrol car is transferred to kinetic energy?
Approximately 20-30% of the chemical energy in the fuel of a petrol car is transferred to kinetic energy to propel the vehicle. The rest is lost as heat through various forms of energy loss like friction, exhaust, and other inefficiencies in the engine and drivetrain.
What Type of energy transformation occur in an iron?
When an iron is heated, the electrical energy is transformed into thermal energy. The atoms in the iron vibrate faster and collide with one another, leading to an increase in temperature.
When we need energy but have low carbohydrate intake, our liver can produce glucose through a process called gluconeogenesis. This process converts non-carbohydrate sources like amino acids and glycerol into glucose, which can then be used for energy production.
Should alternative energy be used instead of traditional energy?
Vague question. "Should" implies personal opinion. For the future of sustainability for the planet, it doesn't matter what type we use at all. In my opinion we will use what is available, and what is available is controlled by profit interests at this time. We "should" do what we have to do to survive.
What Energy from the sun is energy?
Energy from the sun is called solar energy. Solar energy is light energy.
How much energy does a 150 watt light bulb use each minute?
The definition of a Watt is 1 Joule/second. Therefore:
150W * 60 Sec = 9000 Joules / minute.
In units more applicable home energy use, 9000 Joules/minute equals .0025 Kilowatt Hours (KWh)/minute.
On a cost basis, if for example, electricity from a power company costs $.20 per KWh, the 150W light bulb costs 3 cents per hour to use.
What energy is produced when a rubber band vibrates with full explanation?
When a rubber band vibrates, it produces mechanical energy. This type of energy comes from the potential energy stored in the stretched rubber band being converted into kinetic energy as it vibrates back and forth. The movement of the rubber band creates sound waves in the air which are a form of mechanical energy.
What part of the IL produce the light radiant energy?
The electrons in the IPL, or even the noble gas ions in the PLs of the cable, can produce light radiation through excitation and de-excitation processes.
Where do chemotrophs get their energy?
Chemotrophs obtain their energy by breaking down and utilizing organic or inorganic molecules through chemical reactions. This process allows them to extract energy for their growth and metabolic processes. Examples of chemotrophs include certain bacteria and archaea that do not require sunlight for energy production.
What kind of energy transformation occur in the sun?
In the sun, nuclear fusion converts hydrogen into helium, releasing large amounts of energy in the form of heat and light. This transformation of nuclear energy into radiant energy powers the sun and sustains life on Earth.
What device converts electrical energy into motion in the home?
An electric motor is the device that converts electrical energy into motion in the home. It is commonly found in appliances like fans, refrigerators, and washing machines to power their mechanical components.
In which position would an object have the GREATER amount of potential energy?
An object would have greater potential energy when positioned higher above the ground due to its increased gravitational potential energy.
What is the Energy transformations of a laptop?
electrical, from charging it, sound energy from speakers, mechanical energy from keyboard and mouse, thermal from when the laptop heats up or overheats, electromagnetic/light energy from the screen/moniter
How Kinetic energy is best described as?
Kinetic energy is the energy an object possesses due to its motion. It is directly proportional to an object's mass and velocity, meaning that heavier objects moving faster have more kinetic energy. This energy is described as the ability to do work or cause a change in a system.
What objects have no kinetic energy?
Objects that are at rest have no kinetic energy. Additionally, objects that have come to a complete stop after moving previously also have no kinetic energy.
organic compounds
What form of energy does the water have due to the random motion of its particles?
The water has kinetic energy due to the random motion of its particles. This energy is derived from the movement of the water molecules as they vibrate and rotate.
What is the function of a generator is to change mechanical energy?
The function of a generator is to convert mechanical energy into electrical energy. This is achieved through the principle of electromagnetic induction, where the rotation of a coil within a magnetic field induces an electric current in the wire.
Conduction is the transfer of thermal energy through the motion of particles, caused by temperature differences. It occurs in solids, liquids, and gases when atoms or molecules collide with each other, transferring heat energy.
What is the The energy stored in a compound is called?
The energy stored in a compound is called chemical potential energy. This energy is released during a chemical reaction when bonds are broken and new bonds are formed.
What energy transformations occur in a match?
When a match is struck, the friction between the match head and the striking surface generates heat energy. This heat energy causes the match head to ignite, which produces light and thermal energy. Additionally, some chemical potential energy stored in the match head is converted to thermal energy during combustion.
Is cutting paper a thermal energy?
No, cutting paper does not involve thermal energy. Cutting paper is a mechanical process where physical force is applied to separate the paper fibers. Thermal energy is associated with heat and is not involved in cutting paper.
Where is the energy I a polysaccharide stored?
The energy in a polysaccharide is stored within the chemical bonds between the glucose molecules that make up the polysaccharide. When these bonds are broken through processes like digestion, the stored energy is released and can be utilized by the body for various functions.
What is the same as measuring energy?
Measuring energy is equivalent to measuring work done, as both are quantifications of the ability to perform tasks or cause changes. Energy can exist in different forms, such as kinetic, potential, or thermal energy, and can be measured in joules or calories.
