How are calorie and joule similar and different?

User Avatar

Asked by Wiki User

They are both an measure of chemical energy

However,

Calorie is an old-fashioned Imperial system of enertgy measure

Joules in the modern S.I. system of energy measure.

The converskion factor between them is 1 cal = 4.184 J

How is the chemical energy in fossil fuels changed to electricity energy?

User Avatar

Asked by Wiki User

The fossil fuel is combusted in a boiler.

In doing so the boiler is filled with water; it boils ; and forms steam under pressure.

This pressurised steam is passed from the boiler to a turbine , which the steam makes the turbine rotate.

This turbine rotation is connected to a long shaft made of magnetised iron , which . This magnetised iron is rotated inside a coil of wire.. Remember when rotating a magnet inside a wire coil makes the electrons in the wire coil move, hence electricity.

In cellular respiration, the process that converts chemical energy into a usable form is ATP synthesis. Adenosine Triphosphate (ATP) molecules store and transport energy within cells. Through a series of biochemical reactions, ATP synthesis occurs in the mitochondria, transforming energy from glucose into ATP. Learn the intricacies of this vital process in my free course on cellular energy production. Join now to delve deeper into the mechanisms behind ATP synthesis, empowering your understanding of energy conversion within living organisms.

NCV and GCV of coal?

User Avatar

Asked by Wiki User

net calorific value and gross calorific value

GCV to NCV conversion:

- Using the following IPCC formulae determine the NCV of those fortnightly samples

- NCV = GCV - 0.212H - 0.0245M - 0.0008O

- Where H - Percentage of Hydrogen, M - Percentage of Moisture and O - Percentage of Oxygen (as determined from the ultimate analysis report)

- Please note that here GCV and NCV are in Mega Joule/kg, therefore it is required to do the necessary unit adjustments (1kcal/kg = (4.186/10^3) = 0.004186 MJ/kg)

Assuming GCV = 18.4017MJ/kg, O =9.23%, H = 3.63%, M=7.45% (Source: Coal analysis report conducted independent testing laboratory - ' National Council for cement and building materials')

How do plants convert light from the sun into energy?

User Avatar

Asked by Wiki User

The short answer is photosynthesis! But what does that really mean?

In a nutshell, plant cells have organelles (the "organs" or a cell) called chloroplasts that have green pigments called chlorophyll located inside of them. The chlorophyll are arranged in a way that allows the energy received from sunlight to excite their electrons and pass an electron from pigment to pigment until it reaches the reaction center (a special chlorophyll A). The above mentioned is referred to as the 'light dependant stage.' The very first electron is donated by a water molecule, splitting it into hydrogen ions and oxygen molecules (which plants release for us to breath). This is why plants need water!

This electron is then passed along an electron transport chain consisting many pignments embedded in the thylakoid membrane (little stacks within a chloroplast). This chain uses electrons to form ATP (potential energy stored in a chemical compound) and NADPH (an electron carrier). They will come back into play in a short bit...

The 'dark' or 'light independent stage' starts when the carbon dioxide absorbed by plants from the atmosphere enters a series of reactions collectively called the Calvin Cycle. Through a handful of reactions, carbon dioxide is transformed into various compounds and then back again, in a cycle. The ATP and NADPH created in the transport chain earlier provide the electrons needed to change up the compounds. Half way during the cycle, glucose is released. This is the 'sugar' that plants produced. For example, the sweet taste of fruit. This is is essentially the food 'energy' that humans need to survive.

To go beyond your question a bit, the energy that humans get from eating plants comes from the opposite process of photosynthesis; cellular respiration. Here, through a number of different chemical reactions, the glucose molecules are broken back down and give ATP (remember, this is the potential energy molecule). ATP (or adenosine triphosphate) releases lots of energy when it is broken down into ADP + P.

There you have it - how plants convert light from the sun into energy!

Plants have specialized organelles in their cells called chloroplasts that perform photosynthesis. Photosynthesis is the process that takes light energy from the sun and binds that energy into glucose.

What energy is being tranferred when a chicken eats corn kernals?

User Avatar

Asked by Wiki User

Corn is an excellent source of vitamin B1, B5, C, E, folic acid, magnesium and phosphorus. It is low in protein, due to the minimal content of the amino acids lysine and tryptophan. Corn is a good source of complex carbohydrates, fibre, and healthful essential fatty acids. Nutritional energy would be the word you are looking for.

Where is phone energy produced?

User Avatar

Asked by Wiki User

Phone energy is a little known source of energy but it is getting popular day by day. As it's name suggest phone energy can be extracted from your phone lines at home. As you know phone lines remains live even your home electricity is off for some reason. You can make use of this phone line energy. To do that you need a system. In the market there are some guides available for that. There are a number of sites which can give detailed information about how to extract phone energy.

What is chemical energy in a battery transformed into?

User Avatar

Asked by Wiki User

The electrical energy is changed into other kinds of energy in the load connected to the battery.

The energy can be mechanical (rotation or movement against friction, inertia, and gravity).

The energy can be radiation (heat, magnetism, light, radio waves, etc.)

Heat is usually not desired.

In every load, some of the energy is inefficiently converted to heat because of the imperfections of the loads we have built to do work for us, all of which must follow the laws of the physical universe.

Describe the energy transformation that takes place in a generator?

User Avatar

Asked by Wiki User

Mechanical energy to electrical energy.

A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical).

Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.

Device that is used to convert solar energy into electricity?

User Avatar

Asked by Wiki User

Solar panels, also known as photovoltaic panels or PV panels, are the devices used to convert solar energy into electricity. These panels consist of multiple solar cells, usually made of silicon, which absorb sunlight and convert it into direct current (DC) electricity. This DC electricity is then converted into alternating current (AC) through an inverter for use in homes, businesses, or the power grid. Solar panels are commonly installed on rooftops or in large solar farms to harness the sun's energy and generate clean and sustainable electricity.
