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.
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.
A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10 2 kJ of work on the system What is the change in internal energy of the system?
3.0 x10 1 kj A system gives off 196 kJ of heat to the surroundings and the surroundings do 4.20 x 10³ kJ of work on the system. What is the change in internal energy of the system? --- 224 kj
What are the 2 heat energy units?
The most popular two heat energy units are: Calorie and BTU (British Thermal Unit).Both these units are obsolete. These days, allforms of energy are measured in joules.
How much energy is required to vaporize 1.5 kg of copper?
1650kj

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.

What does kJ measure?
Energy.
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
Why do you use kilojoules?
We use kJ, MJ, or GJ, because the Joule is a fairly small unit. For example, a 40-Watt light bulb, giving light during one hour, would use 40 x 3600 = 144,000 Joules, or 144 kJ, or 0.144 MJ. This is not a huge amount of energy!We use kJ, MJ, or GJ, because the Joule is a fairly small unit.

In chemistry what does KJ mean?
That is an abbreviation for a kilojoules, a metric measure of energy.
