How much energy is in a gram?
Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~9×1013 joules..
How many grams are in a Joule?
How many grams in 1 joule/metre? The answer is 101.97162129779. We assume you are converting between gram-force and joule/metre. You can view more details on each measurement unit: grams or joule/metre The SI derived unit for force is the newton.
How many calories is one gram?
Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. You can view this information on the bottom of the Nutrition Facts Panel on food packages.
What is E mc2 used for?
Einstein’s greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously.
How much mass is converted to energy in a hydrogen bomb?
MASS-ENERGY CONVERSION In the fission of the uranium nucleus, one-tenth of 1 per cent of the mass is converted into energy; in the fusion of four hydrogen nuclei to form helium, seven- tenths of 1 per cent.
How many joules are in a mole?
Since 1 mole = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214179×1023 particles, or (6.022×10^23 particles/mole), 1.66054×10−24 joule per particle.
Is Joule a SI unit?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.
How many joules are in a kilogram?
89,875,517,873,681,764 joulesOne kilogram (kg) of mass is equivalent to exactly 89,875,517,873,681,764 joules (according to E=mc2 with m = 1 kg and speed of light c = 299,792,458 m/s).
What is E mc2 used to calculate?
This is the most famous equation in the history of equations. It says that the energy (E) in a system (an atom, a person, the solar system) is equal to its total mass (m) multiplied by the square of the speed of light (c, equal to 186,000 miles per second). …
What is E mc2 called?
One of the most famous equations in mathematics comes from special relativity. The equation — E = mc2 — means “energy equals mass times the speed of light squared.” It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.
How do you convert energy into weight?
The energy (e) of a mass to energy conversion equals the mass (m) that was converted multiplied by the speed of light (c) squared. If we choose mass in kilograms and the speed of light in meters per second, then the answer will be in Joules.
How much energy is released when 1g of matter is converted to energy?
Specifically it says that if you convert 1 g of mass to energy, you get 9 x 1020 ergs of energy — (To use this just keep consistent units -i.e. Joules, Meters, Seconds, Kilograms, and Ergs, centimeters, grams, seconds.

Is E mc2 proven?
It’s taken more than a century, but Einstein’s celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists. … The e=mc2 formula shows that mass can be converted into energy, and energy can be converted into mass.
How do you convert joules to Grams?
Solve for “m” in the energy equation by dividing both sides of the equation by (3_10^8)^2. Using the same example, “m” is equal to 5.556_10^-17 kilograms. Convert “m” to grams. There are 1,000 grams in every kilogram, so you can convert 5.556_10^-17 kilograms to grams by multiplying by 1,000.
What can 1 gram of antimatter do?
Antimatter-matter annihilations have the potential to release a huge amount of energy. A gram of antimatter could produce an explosion the size of a nuclear bomb. … Making 1 gram of antimatter would require approximately 25 million billion kilowatt-hours of energy and cost over a million billion dollars.
How much is teaspoon in grams?
four gramsTo be precise, 4.2 grams equals a teaspoon, but the nutrition facts rounds this number down to four grams.
What is measured in ergs?
Erg, unit of energy or work in the centimetre-gram-second system of physical units used in physics; to lift a pound weight one foot requires 1.356 × 107 ergs. It equals the work done by a force of one dyne acting through a distance of one centimetre and is equal to 10-7 joule, the standard unit of work or energy.
