How do you calculate joules in chemistry?
Multiply the mass of the object by its specific heat capacity and by the amount of temperature change. This formula is written H = mcΔT, where ΔT means “change in temperature.” For this example, this would be 500g x 4.19 x 20, or 41,900 joules.
Is kJ G the same as J kg?
» Kilojoule/kilogram Conversions: kJ/kg↔J/g 1 kJ/kg = 1 J/g.
How do you convert kJ kg to kJ?
kJ/kg↔kJ/t 1 kJ/kg = 1000 kJ/t.
How do you convert kg to kJ?
Please provide values below to convert kilogram/joule [kg/J] to kilogram/kilojoule [kg/kJ], or vice versa….Kilogram/joule to Kilogram/kilojoule Conversion Table.
Kilogram/joule [kg/J] | Kilogram/kilojoule [kg/kJ] |
---|---|
0.01 kg/J | 10 kg/kJ |
0.1 kg/J | 100 kg/kJ |
1 kg/J | 1000 kg/kJ |
2 kg/J | 2000 kg/kJ |
How do you find kJ in chemistry?
Calculating energy changes
- = 100 × 4.2 × 20 = 8,400 J.
- It is also useful to remember that 1 kilojoule, 1 kJ, equals 1,000 J.
- Moles of propane burned = 0.5 ÷ 44 = 0.01136.
- So, the molar enthalpy change, ∆H = 8.4 ÷ 0.01136 = 739 kJ/mol.
How do you calculate grams to joules?
Worked example – calculating energy per gram of fuel
- Energy given out = mass of water × 4.2 × temperature change.
- Energy measured in joules, J.
- 4.2 is the specific heat capacity of water, J/g°C.
- Temperature change = temperature of water after heating – temperature of water before heating.
