kJ is kilo Joule. One thousand Joules.
The joule (symbol J), named for James Prescott Joule, is the derived unit of energy in the International System of Units. It is the energy exerted by the force of one newton acting to move an object through a distance of one metre.
1 J = 1 W*s (one Watt second)
One joule in everyday life is approximately:
- the energy required to lift a small apple one meter straight up.
- the energy released when that same apple falls one meter to the ground.
- the energy released as heat by a person at rest, every hundredth of a second.
- one hundredth of the energy a person can receive by drinking a drop of beer.
- the kinetic energy of an adult human moving at a speed of about a handspan every second.

What does kj stand for?
KJ stands for Killjoy.
Is energy kj a nutrience?
kj (kilojoule) is simply a unit to measure energy.
What is the lattice energy for potassium bromide?
The lattice energy for KCl is 715 kJ mol-1.
Kj is used to measure what kind of energy?
KJ is Kilojoule - 1000 Joule. Joule, or a multiple such as KJ or MJ, can be used to measure any kind of energy.
What does kj stand for in food?
it means kilojoules and is the amount of energy transcribed from that food. On all food products it is the law to have thte nutritional information and also have the amount of kJ that it contains hope this helps :)
What does kJ measure?
Energy.
How do you get the kJ solar energy in on hour?
convert 9,158,960 km^2 to kJ
If two atoms are bonded with a bond energy of 212 kJ what must be done to break the bond?
212 kJ of energy must be added. hope this help ya
Is it possible to get more work out of a machine that you put in?
Yes and no. The energy in the universe is constant so you can not get more work out of a system than exists in the system. For example, if there is 20 kJ (kilojoules) of energy that exists in the system in the form of heat, chemical energy, etc... and you put in 5 kJ of energy, it would be possible to get out 10 kJ of energy. It is not possible however to get 30 kJ of energy out of the system because 30 kJ does not exist in the system, and energy can't be created, only transfered.
In chemistry what does KJ mean?
That is an abbreviation for a kilojoules, a metric measure of energy.
How much energy is required to vaporize 2 kg of copper Use the table below and this equation Q Melva?
2200 kj
Why is the unit of energy called a KJ?
Joules, is the basis unit in International Systems of Unit (SI). It defined as energy equivalent to force of 1 Newton acting over distance of 1 meter. This unit of energy can related mechanical energy to heat to electricity and any other forms. The prefix k stand for kilo or 1,000. 1 kJ is thus 1,000 J.
