How much is a energy in joules?
Unit of energy; approximately 4.2 joules
How much energy joules in a peanut?
Yes, there are energy joules in a peanut. One peanut releases 1,880 physicist calories, or 1.88 food calories. Energy is measured in joules. One food calorie equals 4,200 joules. So one peanut has just under 8,000 joules of energy.
How much energy is 500 joules?
500 joules is equal to 368.78 ft-lbf. For example, an object has 500 joules of kinetic energy, when its mass is 10 kg (~22 lbs) and it is traveling at 10 m/s (36 km/h or ~38.2 ft/s). Second example: The muzzle energy of a traveling 9mm bullet is around 500 joules. Third example: An object with mass of 5kg (11 lbs) and which is raised at 10 metres (32.8 ft) has around 500 joules of potential energy. So, 500 joules is quite much. Getting hit with an object which has 500 joules of kinetic energy can be lethal.
How Much energy in joules is expended if a baseball travels 30 meters?
125
Does it take more energy to heat the water to 100 degrees Celsius or to boil it?
q (heat energy in Joules) = mass * specific heat * change in temp 1st problem: q = (100 g H2O)(4.180 J/gC)(100 C - 50 C) = 20900 Joules ---------------------- 2nd problem: q = (100 g H2O)(4.180 J/gC)(70 C - 60 C) = 4180 Joules --------------------- As you can see from 50 C to 100 C takes much more heat energy as one would intuitively think, 20900 J/4180 J = 5 times as much energy.
How much is a energy in joules?
Unit of energy; approximately 4.2 joules
How much energy is needed to melt 0.25 moles of water?
The necessary heat is 9,22 joules.
How many watts of energy are in a gallon of salt water?
A watt is a unit of power (Joules/second: energy / time). I guess it depends on what method you are using to get energy out of the water, as to how much energy is in it.

How much energy in joules will a 230 nutritional calories supply?
230 calories = 962.32 joules
How much energy is required to heat 955 g of water from 20 degrees C to 100 degrees C?
4.1858 joules of energy will raise the temperature of 1 g of water by 1oC. Thus, 4.1858 * 955 * 80 = 319795.12 joules of energy is required to raise the temperature of 955 g of water by 1oC.
How much energy is needed to get a small electromagnet up to 1.6 Tesla it can be in joules watts or volts?
It had better be in joules. Watts and volts are not units of energy. yes, but how many as in ? joules/sec
What contains the most joules of energy a banana or a sausage?
1 calorie is equal to 4.186 joules. sausage is 50 calories or 209.3 joules of energy. banana is 105 calories or 439.53 joules of energy. Therefore a peeled banana contains much more joules of energy than tasty looking sausages. ;)
How much energy in joules must be absorbed to convert to Na all the atoms present in 1mg of gaseous Na when the first ionization energy is 495.8 kj per mol?
21.6 J
How much energy is needed to heat 50 liters of water to 50 degree centigrade?
300 calories, which is equal to about 1255.2 joules
Does it it take more energy to heat the water to 100 degrees celsius or boil it?
If by "boil" you mean have it all evaporate, that takes MUCH more energy. For example, to increase the temperature of one gram of water from 20 to 100 degrees Celsius, you need 4.2 joules/gram/degree times 80 degrees = about 336 joules; then, to evaporate all the water, you need an additional 2257 joules.
How much energy comes from a peanut?
Just under 8,000 joules of energy mate.
