How much work did a system do in kJ when a system absorbs 650 J during a change and the value was -2.37?
The work done by the system can be calculated using the formula: Work = Force × Distance × cos(θ). Since work is given as -2.37 kJ, we convert this value to joules (1 kJ = 1000 J). So, the work done is -2.37 kJ × 1000 J/kJ = -2370 J. Therefore, the work done by the system when it absorbs 650 J of energy during a change is -2370 J + 650 J = -1720 J or -1.72 kJ.

What is 3923.7552 J into Kj?
To convert joules to kilojoules, divide by 1000. Therefore, 3923.7552 J is equal to 3.9238 kJ.
Energy in one mole of glucose in joules?
The energy content of one mole of glucose is approximately 2,810 kilojoules (kJ) or 2,810,000 joules (J).
k j equals j but how is that?
The energy E in joules (J) is equal to 1 kilojoule times 1000: E (J) = 1kJ × 1000 = 1000J . So 1 kilojoule (kJ) is equal to 1000 joules (J): 1 kJ = 1000 J .
How much heat must be added to raise the temp of .4 kg of water from 20 C to 25 C?
Using the specific heat of water as 4180 J/kg/deg, and q = mC∆T one can calculate the heat needed.q = (0.4 kg)(4180 J/kg/deg)(5 deg) = 8360 J = 8.4 kJ (or 8 kJ to one significant figure)
The initial temperature of 0.8 kg of ice was -5 Celsius. How much energy is needed to cause the ice to start to melt?
specific heat of ice = 2.09 J/g/degree2.09 J/g/deg x 800 g x 5 deg = 8360 J = 8.4 kJ∆Hfusion = 334 J/g0.8kg x 334 J/g x 1000 g/kg x 1 kJ/1000 J = 267 kJ8.4 kJ + 267 kJ = 275.4 kJ
How do you mention kilojoule units?
kJ for kilojoules and J for joules.

If 3 moles of a compound use 12 J of energy in a reaction what is the H reaction in kJmol?
12 J/3 moles = 4 J/mole. Thus, H of reaction in kJ/mole = 0.004 kJ/mole
