You cannot.
A kilogram is a measure of mass while a Joule is a measure of energy. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
The calorific value of diesel is around 42.7 Mega Joules per kilogram.
A 150-pound man (68 kg) contains approximately 2.8 x 10^6 Joules of energy, based on the average energy content of the human body being around 10 MJ/kg.
There are 3.6 million joules in one kilowatt-hour.
Momentum does not have the same units as the others. Kinetic energy is measured in joules, potential energy in joules, work in joules, but momentum is measured in kilogram meters per second (kg m/s).
To determine the volume of water that can be boiled using 3.0 kg of energy, we first convert the energy from kilograms to joules. Assuming the energy is in kilograms of mass equivalent (using E=mc²), 3.0 kg of energy is equivalent to about 2.7 x 10^16 joules. The energy required to boil water is approximately 2,260 joules per gram (the latent heat of vaporization). Thus, dividing the total energy by the energy needed to boil water gives you about 11,900,000 grams, or approximately 11,900 liters of water.
The momentum of 5 kg m/s is equivalent to 25 joules.
The heat of vaporization for mercury is about 59.11 kJ/kg. To convert this to joules/kg, multiply by 1000 to get 59,110 J/kg. Therefore, for 0.06 kg of mercury, the energy released when condensed to a liquid at the same temperature would be 0.06 kg * 59,110 J/kg = 3,546.6 Joules.
The unit for specific latent heat is J Kg-1(Joules per Kilogram)
The calorific value of diesel is around 42.7 Mega Joules per kilogram.
2000 joules
The amount of energy present in 1 kg of water is typically around 4,186,000 joules at room temperature. This value represents the energy required to raise the temperature of 1 kg of water by 1 degree Celsius.
A 150-pound man (68 kg) contains approximately 2.8 x 10^6 Joules of energy, based on the average energy content of the human body being around 10 MJ/kg.
On average, wood has a heating value of around 16-20 megajoules per kilogram (MJ/kg). This means that a kilogram of wood contains about 16,000-20,000 joules of energy.
A gram of ANFO explosive yields about 6300 Joules of energy. The value is usually expressed as 6.3 MJ/kg.
There are 3.6 million joules in one kilowatt-hour.
The heat of vaporization of mercury is 59.11 kJ/kg. To convert this to joules, we multiply by 1000, which gives us 59,110 J/kg. Therefore, the energy released when 0.06 kg of mercury is condensed to a liquid at the same temperature would be 0.06 kg * 59,110 J/kg = 3,546.6 J.
KE = 1/2 M V2 = 1/2 (2) (20)2 = 400 kg-m2/sec2 = 400 joules
